Linear Electric Motor

[@fosforito1987]

please ignore all the negative comments. Thank you for your time to explain a few things to younger generations. Please Dont stop making these videos.

[@electricandmagneticfields2314]

Thank for you kind words of encouragement. I am working on a couple more demonstrations this summer.

[@brnmick]

This is why I love youtube. Thanks for the really cool demonstration as well as explanation.

[@electricandmagneticfields2314]

***** You are welcome, and thanks for the kind words.

[@DILLIPKUMARSAHOOIITM]

Such a beautiful and simple explanation of the principle behind linear electric motor. This approach makes science and engineering much more interesting. Thanks a ton. Keep making more videos like these.

[@electricandmagneticfields2314]

DILLIP KUMAR SAHOO Thanks for the kind words. I do plan on adding videos.

[@gustavomonge1785]

👍

[@swh19]

Awesome and thank you!! Please upload more simple experiments to illustrate the important concepts behind them.

[@electricandmagneticfields2314]

I have about 50 uploaded now. I try to add a few every year.

[@yt.user-zull]

Explained so nicely! 👍

[@carlosgianpaulrinconruiz5558]

Nice explanation Michael

[@ilchgereldash4133]

Very good, thank you. Could you explain does it work without a battery?

[@electricandmagneticfields2314]

You need that battery. The battery causes a current in the coil that produces a magnetic field that propels the magnets on the two ends of the battery.

[@Spiegelradtransformation]

So cool. I try to built a linear Engine on my Bianchi Bicycle Rim.

[@ReBcSyKeE]

Thank you so much for this great explanation! :)

[@niketanjha]

Awesome work (y) and Nice explain, really likes ur work please keep it up. :)

[@gustavomonge1785]

Thanks A great explanation !!

[@sau002]

Excellent explanation.

[@190890famda]

Thank you for Your great explanation. Everything is make sense, except one thing. Did You use insulated/emailed wire to form the coil? unless the wire is bare, I can't find a way for electric current to flow through it.

[@electricandmagneticfields2314]

It is bare copper wire

[@wisdom_wellness365]

Very nice! I like it!

[@electricandmagneticfields2314]

Thanks!

[@Bendigo1]

Would this work if the coil is powered insead of the magnets? Would the magnetic field cancel out?

[@billbrown994]

Thank you Professor.

[@electricandmagneticfields2314]

You are welcome!

[@tamisonsresources3396]

Can the battery be replaced with a bolt and nut?

[@johnchisholm7350]

You nearly solved my ten year old problem! I want to spin a bicycle wheel suspended in a frame, so l can’t use a coil on the rim and fixed magnets. What is my next stop? John from oz

[@Kikutuca]

Great video

[@nuigurumisama]

Would this still work with the coil wrapped around the pipe? I want something a little more sturdy than a coil of wire.

[@nuigurumisama]

Never mind, I would have to somehow stick the coil inside the pipe for the magnets to make contact with the coil.

[@electricandmagneticfields2314]

You could get thicker copper wire so that once you wound it into a coil it would be firmer. That is what I plan to do at some point because what I have is a little too flimsy. I used 20 gauge wire.

[@nandagopaliyengar1258]

wondeful video

[@electricandmagneticfields2314]

Nandagopal Iyengar Thank You!

[@bitsurfer0101]

Would it behave differently if you had a ring magnet instead of a disc?

[@electricandmagneticfields2314]

It would work the same.

[@kenfuciusfpv2800]

Question, could you massively charge some capacitor (of unknown type to me) and replace the batter with that, and somehow lighten the hard magnets, and get much more speed?

[@electricandmagneticfields2314]

A capacitor would discharge almost instantly. So you would get one big shot. Similar to what is done in a rail gun.

[@vivekkoli9808]

what is the gauge of copper wire?

[@electricandmagneticfields2314]

The wire was 20 SWG (19 AWG). If I were to do it again I would get a little bit thicker wire, this was just a little too flimsy.

[@seancsnm]

Not 100% sure I understand how this is working. Is the copper wire coil un-insulated?

[@electricandmagneticfields2314]

Correct, it is bare copper wire. That allows a current to flow in the section where the battery and magnets are, so only the part of the coil between the two magnets, resulting in a magnetic field produced by that section of the coil.

[@seancsnm]

Ok, makes much more sense that way. It just looked a lot like magnet wire from the video.

[@500nozomi]

thankyou... thankyou so much...

[@rifaiadityapp]

ukur piro ngab?

[@tonystarks315]

I would call it Faradays Slinky

[@electricandmagneticfields2314]

Good one!

[@alexalbrecht3179]

Thank you

[@rolandjollivet38]

your magnets are labelled incorrectly. It should be NS- NS for the flux lines as shown

[@electricandmagneticfields2314]

The magnetic fields I am showing are not from the magnets but from the current flowing in the coil.

[@justinowen6055]

Wow

[@accidentaliitian6063]

Thankyou sir

[@ahmetdede2]

excuse me Michael! that "s right...my pronounce english is poor ...coil is unisolated ? I can"t listen...Ok.Excellent idea...congratulation

[@electricandmagneticfields2314]

+Ahmet Dede The coil is not insulated, it is bare copper.

[@ahmetdede2]

thanks Michael;I can't understand that english spoken...My english is very poor..

[@challsyn5829]

this is a coil gun or Gauss gun in a nutshell

[@Galv140577]

Now do the opposite and make it generate power to light an LED

[@Jkauppa]

pure dc homopolar motors and generators, true brushless, not bldc fake dc (actually ac)

[@Jkauppa]

instead a network powered coil train

[@Jkauppa]

battery is on the mail line, rails, not the projectile train itself

[@Jkauppa]

single lead wire in the tube after the projectile train, like line controller missile, then the other wire, the coil, will be the other electrode

[@Jkauppa]

you can have the whole coil energized whole time, no rise time, then the additional wire(s) will provide possible electromagnet current, but if you run the whole coil all the time, there is no need for the battery part of the train, just the magnets on a magnetic metal or even just the magnets themselves, in some container

[@racketman2u]

the captioning needs work - just about every sentence is wrong and making gibberish.

[@electricandmagneticfields2314]

+racketman2u I'm not sure what you are referring to as there is no captioning on this video.
