Induced Eddy Currents in Train Brakes + Lenz's Law - Physics Made Easy! ( BU - PY 106 )

Here's the first Physics Made Easy video with me in it! I discuss induced currents and how they are generated and used in train brakes! This video was made as part of my LA (Learning Assistant) job for BU's Physics Dept. and Physics II course.
If this video is helpful, don't just keep it to yourself, tell your fellow physics friends. We also are open to feedback so leave some so we know if we are on the right track or if you'd like to see something done differently. :]

[@ThomasHaberkorn]

pretty great, keep coming back to this video

[@OrgoMadeEasy]

Thank you @ThomasHaberkorn ! Glad it’s still helpful haha

[@maktutors9481]

Finally get it thanks a lot

[@maragathambhuvanesh8029]

very nice thanks a lot

[@ACKtube-of3qf]

thank you very much

[@kimberlyannnn]

Woah Frank ;) Wish you could be my personal Physics tutor! But in all seriousness, thank you for explaining Eddy Currents!

[@OrgoMadeEasy]

Kimberly Ann Haha no problem Kimberly! I actually do offer tutoring for Physics/Orgo though. But unfortunately I'm already at a full schedule. But I'm sure you'll do fine in Physics. :D

[@kimberlyannnn]

Damn! Whoever has you as a tutor is very lucky.. I think I'd get way too distracted, though ;) Thanks again!

[@louismarr3725]

+Kimberly Ann Hopefully he sent you a DM after this comment

[@OrgoMadeEasy]

@@louismarr3725 just saw this haha, No DMs were sent 😂😂

[@Integrelle]

University of British Columbia Eng student here to say thank you! lol

[@mohammedazzan7529]

Which engineer are u in??

[@sgeo347]

Totally not to do with train brakes here, but this helped me write an essay on MR Physics, so thanks!

[@saggy5820]

Thks bro

[@jorgemercent2995]

WARNING. The explaination of the force genrated is wishy washy; the forces generated DO NOT point towards the center of the wheel. Also the direction of the eddy current is NOT JUST counter clockwise around the wheel as suggested @2:51; there are actually 2 sets of eddy currents. For better explaination of what is really happening, refer to: ua-cam.com/video/H310MWSWxF0/v-deo.html. The force is generated due to interation between these 2 sets of magnetic poles generated by induced 2 eddy currents of diff direction AND the poles of the magnetic brake; this force directly opposes the force of wheel movement.

thanks

[@AVK_ND]

Finding of direction using right hand rule is not clear...

[@kerenarteaga2112]

buena explicación :)

[@chinanumberone7723]

I love you

[@nicholasngzhuoxun385]

As the green circle exits the magnetic field region, am I right to say that the train still brakes?

[@varshan2132]

Some other green circle enters.

[@rahulmaurya3886]

Account for the heat produced as well, its practically impossible at great speeds.

[@abdelrahmangamalmahdy]

but wait, aren't all the forces pointing towards the center and hence canceling each other ?!

[@abdelrahmangamalmahdy]

oh yeah i got it.. that's just because the magnetic field didn't enter the entire region yet!

[@varunyadav479]

but , according to fleming right-hand rule , thumb points the direction of current and curl points the magnetic field... so your whole concept is wrong... if not plz explain.

[@OrgoMadeEasy]

Woops! Forgot to reply earlier but I'm just using a different right hand rule that I learned at Boston University, should all still work out fine.

[@bluiflip]

This really can't be understood, thoroughly, in a 2D format.

[@hawaslianas]

That's terrible

[@crimsonkiras]

senpai pls notice me

[@callit3580]

Lol
