How to magnetize a screwdriver January 17, 2018

[@RGSPrideTILE]

Exactly what I was looking for. thanks for refreshing my memory

[@ShahidR82]

def the hard way. just use a magnet and slide it across the screwdriver a few times. magnetic parts tray, speaker, etc. works just as well, and done in a few seconds.

[@deim0s243]

I was looking at videos of electromagnetic induction learning some theory, but this is the voice of experience talking! Great video, thank you for sharing.

[@farisesad6198]

I am a physics teacher and I know the reason for the weak magnetization that I got and the reason is a way to loosen the wire around the screwdriver. You wrapped the wire and then wrapped another layer on top of the first and this is the error. To make one coil, and another solution. If you finish winding the first coil, go back with the wire straight over the first coil to the beginning of the first coil, then start winding the wire to give two coils with the same direction. Thank you for your effort.

[@pouncerminned863]

are you saying once you finish the first coil, make a second one starting where you started the first one? in this video it shows first coil, then starting new coil at location where the first one ended?

[@wingerrrrrrrrr]

It doesn't matter if you wind the second layer from the tip to the handle vs handle to tip, as long as it's around in the same direction you started with, either clockwise or counterclockwise. The magnetic flux will still get generated in the same direction.

[@rickeykeeton71]

A buddy was talking about buying a magnetized or magnetize he screwdrivers today by rubbing them on a magnet. I didn’t get a chance to tell him about how I had seen done probably about 59 years ago. I was not sure whether the wire still had the insulated covering on it or not. Glad I came across this video. I have some I need to magnetize myself.

[@57bagre]

Thanks for watching.

[@wingerrrrrrrrr]

Wire definitely has to be insulated or it wouldn't work.

[@damexican1671]

Here's another way to magnetize a screwdriver my friend, you can run a screwdriver onto one side of a good size speaker magnet to magnetize it & to demagnetize it just run the screwdriver on the opposite side of it 👊 Blessings everyone 🙋

[@ramraja7796]

Much better and this way, you will not damage the battery , putting short across a battery does not not do it any good.

[@inkstain7193]

Yep. Took 5 sec.

[@drewrinker2071]

@@ramraja7796 yes, but I think by using an electromagnetic coil you end up being a much stronger magnetic screwdriver

[@stanpatterson5033]

Yep, I learned the trick in junior-high. The science curriculum included mandatory science fair projects, every student had to do one in class (each year grade 6 thru 8), and could voluntarily enter his/her project into the actual science fair competition afterward. One year, I did electromagnets. I just used Bell wire and a piece of round solid stock, and one of the old 6v lantern batteries (the rectangular ones that had screw terminals). My Dad was the "supplier" of my equipment. I had to read books and encyclopedia(s) to get the theory and wording, but he taught the practical end of it. Also learned how to use an existing magnet to either temporarily or permanently magnetize screwdrivers. Sometimes, it's a darn valuable thing to be able to have control over the screw or bolt down in the worst hard-to-reach place. I do have a bench battery, and will now try your double-wrap method, because I've never done it that way before. Has winter's icy grip eased off in your neck of the woods yet? Had a few "easy" days up here where it warmed up to around the 20's, and dumped more snow on us.

[@57bagre]

Today the weather is supposed to get better, we've been in the single digits for a week now and it's time to go above normal for a bit. high in the 40s low in the upper 20s for a few days.

[@ToThePoint690]

best video after long time..

[@57bagre]

Thanks for watching.

[@glencouls]

Thanks Gordon great video, I remember doing this middle school with smaller batteries but our results didn't last very long. Will the usage of the 12v battery keep the magnetism on the screw driver forever, or how long can we expect the magnetism to keep its hold? Thanks again for any insight you can provide here towards my question, cool channel.

[@weatherphobia]

Just take a regular magnet. Slide it down the screwdriver away from the handle to the tip about 8-12 times. THEN so how magnetic it is, much stronger and lasts up to 4 years.

[@someuser4166]

I have done old weak fridge magnets. Could I do this to strengthen them?

[@saidbakr]

You exactly need motors coiling wires, it is thin, isolated and could be wrapped easily to be touched the driver with multiple rotations.

[@petemoss9693]

Hey Gordon . . . You just reminded me of when I was a kid when my grandfather taught me this trick - thanks for the memory -

[@beatriceschillingrc8020]

I was standing on a roof last month in an unnatural position trying to get some sheet metal screws in place (hex head #8's) with a 1/4" socket adapter. Neither the socket adapter or the socket itself was magnetized of course. (almost in tears after dropping multiple screws, never to be seen again, thinking, "I wished I had tried harder in school) I'm going to try this with the adapter and see if I can get the sheet metal screw to stay somewhat in place in the socket. (With my luck, which is none, the screws are some type of alloy that doesn't attract to magnets...) But thank you for the video. I've got a bunch of ultra small screwdrivers for my RC airplane addiction that I'd love to have magnetized. Some of the screws are the size of a grain of rice. (They sell magnetized small screwdrivers, but what's the fun in that when you have a battery, 12-16 gauge wire and a fire extinguisher?)

[@57bagre]

I have used a little grease to stick small screws and bolts to a socket and also on a bigger bolt I will use a piece of electric tape around the socket and the edge of the bolt.

[@scamper_van8470]

mine its guess,wouldn't be better job if you do the same but with a lower voltage lets say 1.5 - 2 V??? and for a longer time than 2 seconds. any way thanks for sharing,i will test that method by magnetizing the rotor of an electric motor with copper wires wrapped inside the rotor.

[@RobertJohnson-jf7up]

Thank you may have saved my

[@williamzoom]

I usually just slide a magnet from the handle to the tip a few times to give it enough to hold a screw:)

[@57bagre]

That works too but not as strong as this, you can also just stick a small magnet on the blade near the tip and that works for a temporary.

[@williamzoom]

I used my good rare earth magnets to make a catch for the door I made for the shop telehandler :(

[@mjh5437]

Sliding a magnet along didn`t work on some of my screwdrivers,I guess that means they`re made of an alloy?

[@chessguru900]

As the current flows through the wire it produces magnetic induction. It is not a lasting solution as the electrons discharge over the time and screwdrivers lose their magnetic properties.

Can you help my sir? I have problem . I have R terminal starter selenoid delco remy type My car is old opel gm based engin from the 80s that thing has gm ignition module 4 pin and induction triger on distributor I do have singel hei coil E core type I also have positive linear voltage regulator in my dash bord suposedly that thing controls voltage going to my coil but I want to use that R terminal for voltage bypass on start up engin when its cold. I cant my fuse pop for dashboard how do I bypass this problem It apeares to by polarity problem based. I did once start my car instead of s terminal I acidentaly put the R terminal wire my car starter fine even tought slovly cranking I experianced like some sort of bether fuel economy even tought I dont know why? So I dont understand what is hapening? I did use some diode and peace of wire and tried to use that R terminal and diferent places on my ignition coil I actualy have 4 independent pins on my E cory type ignition coil so I dont understand what hinders my to use that selenoid? Is my 4 pin gm ignition module polarity senzitibe ore my dashboard regulator? How can I make my self non polarity sensitive triger module ?

[@57bagre]

As I remember, that R terminal on the solenoid was used as a ballast resistor or maybe to bypass an integrated resistor for the old points and condenser system because the starter could rob too much power from the ignition system on cold starting, the ignition ran on lower power full time but would run on full power while cranking the starter, if you ran the ignition full time on full power it would burn out the points and overheat the coil prematurely. I would just run your system the way the engineers designed it.

[@whyWontULetMeUseThis]

You can also plug it into a socket, but it’ll trip the breaker

[@kingofspades5098]

That’s really cool. Is it possible to do the same thing with sockets? That would be really useful on a 1/4 drive for taking off panels.

[@57bagre]

sure they will magnetize but only very small sockets will hold on to a bolt. I recommend using a piece of electric tape around the edge of the socket just barely on the edge of the bolt so as not to pinch the tape under the head of the bolt and in some cases continue the tape on up the socket extension a couple turns so you don't pull the extension out of the socket when the bolt is tight. I also sometimes just pack a little sticky grease in the socket to glue the bolt in.

[@speedmaster001]

How long does the magnetic property hold after doing this?

[@57bagre]

many years, you can always do it again if you want.

[@digitalrok5730]

Great vid does the wire need to be insulated for it to work Thanks

[@57bagre]

Yes it does

[@ricardoelectronicsrepair]

Thank you. It worked.

[@electriccity919]

Does a magnet have an expiration date?

[@nor4277]

My dad did that,except he laid the screw drive down counted to three.best idea I have seen so far

[@57bagre]

Thanks for watching.

[@ericcorse]

Like the other folks i learned to do this in Jr. High and just by sliding a magnet along the screwdriver. This looks to be more effective.

[@57bagre]

Yep, that's about when I learned it I think. The guys that didn't learn it either forgot it or for some reason just didn't get it. So here's a refresher course on the subject.

[@cristymcgowan5690]

Awesome! It worked! Thanks 😊

Love your videos Gordon. I stumbled upon your channel recently looking up Detroit Engine Rebuilding. While going through the series of Engine videos I noticed the name of the company you are leased to. I actually live just north of Edwardsville myself and have been a truck driver for 17 years. I'd love to meet up someday and buy you a cup of coffee and talk shop and maybe give you a hand with a repair sometime.

[@jonathandweber2006]

And then what he said at 5:47.

[@mjh5437]

Can this be done when the battery is still in the car and connected to it or will that also blow out the cars electrics?

[@57bagre]

Yes you can do it from the car, lawn mower or whatever while installed.

[@mjh5437]

OK Thanx.

[@wingerrrrrrrrr]

You could probably use that battery tester to complete the connection to the wire coil, instead of arcing it

[@lucasflamino925]

I never knew you could do it this way. I always just take a magnet and rub it on the end of the secrewdriver to hold a screw.

[@maloosecat123]

I tried magnetizing some deep 10 mm sockets but they didn't magnetize like with screwdrivers...anyone know why?

[@57bagre]

do it again with a couple more wraps of wire or just stick a small magnet on the side of your socket when you're using it if you have room to do so, the socket will conduct the magnetic field and help to hold the nut. Sometimes I stuff grease in a socket to hold a nut or bolt.

[@srikanthbhukya1803]

[@wonnie46403]

Could you do multiple screw drivers at one time?

lasts a lifetime unless you demagnetize it

[@marlongeli1586]

You didnt test first the philips screw showing that theres no magnetin it...

[@Uneedhelp91]

I wonder if you could do that with a tape eraser.

That works to demagnetize, not magnetize things.

Uhhh....isn't there a safer way than using a wire as a resistor on a shorted connection???

[@57bagre]

[@wingerrrrrrrrr]

If you had to do it a lot for some reason, you could use connect the coil in series with a battery load tester, which draws about 100A. Just flick the switch to deliver the current.

You wrap your wires tight. I have , I think a 10 gauge wire that I wrapped around a broom handle. It's about 10 inches long with about 6 inches at each end. I just insert all of the metal in the winding and touch one end of the car battery and then quickly touch and pull away the other end. The screwdriver really has a strong pull.

[@57bagre]

I think I learned it in high school.

[@Confused_Philosopher]

what he is doing is not recomended . that is an acid battery and sparking near a car battery is not a good thing to do because they can and have exploded from sparks which is why you connect the ground last to a metal part of the car and not the battery. That is to avoid the danger of igniting the hydrogen gas that acid and led batteries give off.. The best and easiest way is to take a fairly good magnet , say one frofm anold tube TV, and just let the screw driver lay on it. Or a nother way is to line up one end towards north and of course the the onther end is south then hit the screwdriver in the middle a couple time fairly hard.

[@usdpaulp]

That's a wicked cool trick. Do they stay magnetize forever or do they lose it after a little while?
