That is why Stainless (400 Series) is slightly Magnetic.

Very interesting Mr. Pete. As children my brother discovered that a particular dry cell battery could be squeezed in a vice and we'd get drop of mercury from them. We save the mercury to play with, shining up dimes and stomping on drops of it to listen to it pop. We survived such foolishness.

[@kiloton1920]

That wasn’t mercury

[@danbreyfogle8486]

@@kiloton1920 It sure was, this was in 1962/3 when there was a line of batteries (AA and AAA) that my Dad removed from radio equipment he was repairing. In fact in 2016 when he passed away and I cleaned out his radio repair shop he had a box of those old used batteries. I took them to the hazardous waste depot to have them properly disposed of.

[@ellieprice3396]

We used to play with mercury from broken thermometers the same way. We liked to rub the mercury on pennies to make them look like dimes. That was back when dimes were worth a dollar and mercury was something to play with. When was the last time anyone used red "mercurochrome" on cuts and burns? I'm assuming from the name that it contained both mercury and chrome.

[@kengoddard2357]

Very interesting. I didn’t know nickel was magnetic until now. Thank you 👍

When I was a kid, Canadian nickels still had enough nickel in them that you could pick them up with a magnet. Don't know if this is still the case, but I doubt it given the price of nickel today.

Interesting. I don't remember ever hearing about Paramagnatism before, and I'm almost as old as you!

[@4speed3pedals]

My dad also called the knockouts a slug. You brought back a fond memory, thanks. This video reminded me of a gravity experiment. If you have a small magnet and a length of copper tube say 3 feet through which the magnet will readily fit, allow the magnet to drop though the tube and see if it falls at the same rate as any object dropped at the same time. I believe the power of the magnet may affect the outcome but I myself have never tried it. The magnet will fall noticeably slower through the tube and it is not from contacting the inner wall.

[@mrpete222]

I have done that experiment in another video

[@rwbishop]

On a larger scale many roller coaster brakes work much the same way... and on a smaller scale, thats how old time analog VOM's and some 'beam' type scales are magnetically dampened. There's a lot more to all this.

I still have that same sun growler in my electrical repair shop .I now mainly use it for demagnetizing screwdrivers and such , I also use it to relieve the pain in my digits from arthritis It works for me .Good job sir ,most customers that come in my shop now have no idea what the name of the growler is let alone how to use one. customers my age (Yea I'm old) still come in and ask if I can growler their armature,I also know what buggy whips where used for ,and not on horses .So there you go.

Lyle, I think paramagnetism is why if you drop a ceramin or other strong magnet through a vertically-oriented aluminum tube (relatively close-fitting), it drops *much* more slowly than you would expect.

[@creativerecycling]

About 45 years ago, I started working at Baldor Electric in St. Louis and stayed 12 years. We made a lot of motors with wound armatures. They regularly tested them with growlers.

I still have my old growler too. I had never heard of paramagnatism and found it quite interesting.

[@duron700r]

That was neat! On this same subject, you mentioned in one of the other videos in this series using a soldering gun to unmagnetize/demagnetize tools and such. Works great! Even a new screwdriver with a mag tip really buzzes in the legs of the solder tip. For a moment. Ahhh, no more magnetized tip.

[@billsmith22]

The last material you used being silver solder was in the form of a coil. in other words would form a shorted loop The growler would induce a fairly high current into this loop, This would add to the vibration you are feeling. I am a retired armature winder and very familiar with growlers. They are still used today at any elec. motor repair shop. There are small portable growlers that are used for inside field stators on ac electric motors

[@billsmith22]

the portable growler I used was called a prufex grower and in the form of a wand

They used something similar in physic class to demo paramagnetism. They would drop a copper disk pass a large electromagnet and it would almost hover for a few seconds. We were all in wonder watching it.

Congrats, nice vid, helpful for my knowledge inprovement, used a growler in my younger days. .

[@stevenpressley5956]

I find these videos very interesting... thanks for sharing

[@RichardKinch]

Many of the materials (copper, gold, silver, tin, lead) you cite as being paramagnetic are not. Those are diamagnetic, repelled by an induced magnetic field, not attracted. The effect in either case is very weak in a growler, and what you feel in your hand is merely back electromotive force (EMF) from induced currents in the samples, not paramagnetic or diamagnetic force. Not surprising, because back EMF is what a growler is designed to test such as in diagnosing armatures.

[@johnmolnar2957]

Thank you sir for the video. I find your videos very interesting & informative .I hope you can keep up the great work you do for the community

[@ceptimus]

I don't think you're really demonstrating paramagnetism with the growler. The growler uses AC, and the changing magnetic field induces currents (so-called eddy currents) in any electrically conducting material. Those eddy currents in turn generate a magnetic field that interacts with that from the growler to produce a force. So any conductor, even those that AREN'T paramagnetic will feel a force near the switched-on growler. A paramagnetic material, will even be attracted by a steady magnetic field (such as that from a permanent magnet). There are also diamagnetic materials which are repelled by magnetic fields.

[@littleshopofelectrons4014]

You should also feel the strongest effect with copper because it is the best conductor, other than silver.

[@Basement-Science]

You are correct. If you wanted to show paramagnetism (or diamagnetism), you can do so with a tub of water, a styrofoam "boat" to put the sample on, and a strong neodymium magnet. If you *_hold_* the magnet steadily near the sample, it will be attracted or repelled very slightly depending on the material. If you *_move_* the magnet over the sample instead, those metals with a high electrical conductivity will "follow" the magnet the faster you move it. This is for the same reason those move in the growler.

Most US coins have a 100% copper core and 25% nickel/75% copper cladding. The exceptions are the phosphor brass dollars (Sacagawea and presidential), nickels (25% Ni/75% Cu), and pennies (zinc with thin copper electroplating). If I understand it correctly, that tungsten carbide cutter is probably 10-20% cobalt, which is used to sinter the tungsten carbide particles together. I'm restraining myself from going to eBay and looking for a growler like that. It looks like a really interesting thing to experiment with. I think an old vacuum tube tester would also be an excellent tear down and examination. I remember as a kid going to the King Kwik (like a 7-Eleven) near my house where they had a tube tester in the store.

Try it with Shoe Goo, store bought rubber glue. It's a memory rubber and is magnetic, along with other secret property's. It has a very very long shelf life, but it has to be worked a little before using it. It was used in a child Kings space program (1977*) in his rubber band generator (parented) he used to charge the spaceship batteries with, when in outer space. You can reuse it over and over by resolving it in rocket fuel or 190 proof moonshine (Kara's mountain, song lyrics), you have to use a mold to form it again and again if need be. Cool ! P.S. I am a machinist and tool & die maker, I like you stuff when I'm online with that subject, the what is it stuff is a challenge but fun.

The coin mechanisms used in vending machines and pay phones used a fairly complex sensor system most had three sensors and was used to determine which coin was present or a fake or slug. They were programmable for the various country coin sets. I know, what’s a pay phone?

[@RichardKinch]

Western Electric payphones (called "coin collectors" in the business) comprised what a machinist would call a go-nogo gauge to test thickness and diameters, plus a kinetic bounce to go-nogo on specific gravity and hardness. It basically measured 4 dimensional qualities in an instant, that amounted to a near 100 percent conclusive test of genuineness. The coin had to size right, weigh right, and bounce right to pass. One or more incorrect factors got rejected into the return slot.

[@samtzam3774]

Hi, the experiment is a bit wrong because the magnetic source that you have is pulsating (in grid frequency). So due to this all material with paramagnetic properties and solid consistency (solid bars, liquids, etc. No wires in open loop) will become magnets due to lenz law.

[@floridaflywheelersantiquee7578]

Very interesting thanks for sharing

[@danmenes3143]

Sorry to be a pedant, but this effect is not paramagnetism, but an effect of ordinary classical electromagnetics. The field generated by a growler is A/C, and any conductive material placed in an alternating magnetic field will have eddy currents induced in it, which in turn react with the magnetic field from the growler, resulting in a force that you can feel. One phrase for this is "Lenz's law." The effect that causes the copper to vibrate in the growler is exactly the same as the effect that causes the copper winding of an electric motor to turn. In fact, according to Wikipedia, copper is not paramagnetic. Paramagnetism is a very weak magnetic interaction--much weaker than the effects seen here, but is with fixed magnetic fields. The classic classroom demonstration involves suspending a drop of liquid oxygen between the poles of a powerful magnetic (like the ones salvaged from microwaves). Paramagnetism is a quantum effect found in atoms with odd numbers of unfilled orbitals, and is fundamentally different from the magnetic induction effect you see here.

[@RichardKinch]

Dan, you're correct. Not sure how the venerable and reliable Mr Pete could be so misinformed about magnetic susceptibility, but he's a shop teacher not a physics teacher. Most of the samples he's demonstrating are actually very weakly _diamagnetic_ (negative susceptibility: copper, lead, tin, zinc), not _paramagnetic_ (positive susceptibility). But the di repulsion or para attraction forces in this demonstration are too weak to be felt in the hand. Lenz's Law is all that he is witnessing. See CRC Press _Handbook of Chemistry and Physics_ , "Magnetic susceptibility of the elements and inorganic compounds."

[@BobOBob]

The correct term would be 'magnetic force" if you want a better term to use then power. Fascinating video, most people do not get to play with strong AC magnetic fields like that. But for the principles of magnetic design ,you defiantly want to use the term magnetic force. If someone is studying this then they should quickly realize they can use standard force diagrams with magnets for the design of magnetic hinges, dampers or electromagnetic devices. The proliferation of cheap induction heaters is going to make the shop more interesting and intellectual I think... wireless phone chargers, induction stoves and electromagnetic blacksmithing, stuck bolt removal and brazing devices.. are we in the jetsons yet? At least maybe we won't have idiot plumbers catching houses on fire so much in the future (I love the story about a nail conducting heat into insulation and causing a house fire after torch plumbing repair work... very scary if there are people around that have no concept of insulation and shielding in tight spaces). Plus with this economy and oil politics, getting friendly with electricity and magnetism can help your wallet and possibly country. For instance, I found that using a current transformer is a good way to avoid using gas for straitening sheet metal. You can quickly get a yellow hot 'dime' sized section of sheet metal ready for flame(thermal) hammer straitening without busting out the acetylene... I bet a induction heater might work for this also. The little magnetic latch on my smart phone screen case cover saves me around 20$ a year in corning screen protector glass without making me think about what is in my pockets all the time. Magnetic charge cables are also wonderful IMO. Very simple magnetic devices with high utility. And for those playing/building with magnets, loctite black prism rubberized cyanoacrylate adhesive is wonderful.

[@oooooooooorly]

Turns out metallic mercury is pretty harmless, on account of just not being very bioavailable - you can swallow small amounts of the stuff and it goes right through (I am not suggesting anyone actually do this...). It's organomercury compounds you have to watch out for. Metallic lead is a bit worse, but lead isn't nearly as volatile and as long as you wash your hands after handling the stuff you're fine. Lead paint dust in the air, on the other hand, can be horrific. I wish there were better messaging to the public about what is and is not hazardous with these materials.
