Physics 43 Magnetic Forces on Moving Charges (8 of 26) Torque on a Current Loop

[@Jackpan272]

Just wanted to say a quick thank you. Your illustration is ten times more clear than the one on my textbook.

[@MichelvanBiezen]

Glad it was helpful.

[@johnholme783]

Your videos make an excellent supplement to my physics textbook! Keep up the good work. Much appreciated.

[@valeriereid2337]

Thanks for this very excellent lecture. I just wasn't understanding this from the textbook. So glad I got it now.

[@MichelvanBiezen]

Glad it was helpful!

watching on your website, going through all the magnetism videos, wish I had known about your site when the semester started, not so late in the semester .... better late than never :)

[@wirito]

Same here. It would have made a WORLD of difference!

[@CatsBirds2010]

Your videos are all great! Thanks.

[@MichelvanBiezen]

Glad you like them!

perfect narrating

[@MichelvanBiezen]

Thank you. 🙂

[@markkennedy9767]

Thanks for this. If one section of the loop is fixed as a hinge, can you comment on what the torque of the loop around that hinge would be. I understand that F=mu×B=IABsintheta gives the torque of a free loop as here, but was just wondering if that would be the same torque around a section fixed as a hinge. I suspect not. Can you confirm this. The reason I ask is I'm doing a problem that asks to get an expression for such a torque (due to an unknown B field) around a fixed section as a hinge . And then asks to equate this expression to the torque due to the weight of the loop around that hinge. So we can find the target variable B. If you comment on this, I would really appreciate it.

[@johannstettler9434]

Would there be torque on this circuit as long as the magnetic field is at an angle? Meaning the movement would be harmonic with damping until the circuit settles parallel to the plane, right?

[@MichelvanBiezen]

There will be a torque on the loop as long as the normal to the loop is not parallel to the magnetic field. I would not associate this with "damping".

Welcome to the channel

[@marbrydav9698]

Great explanation

[@nguyennguyenvu9718]

will the torque make the loop turn?

[@MichelvanBiezen]

That is essentially what an electric motor is. (there are off course some design features needed to make it turn) but yes that is what makes it turn.

[@nguyennguyenvu9718]

@@MichelvanBiezen ok thanks for your explaination. Btw great tutorial

[@cansucetin6046]

you are perfect !

[@raginibhayana1117]

Sir the direction of torque due to both the forces would be in same direction?

[@MichelvanBiezen]

That is correct. The current loop is not in mechanical equilibrium.

[@Monya97]

you're amazing

Thanksss

Welcome

1 hour before my exam, feel normal and think i will do okay

[@MichelvanBiezen]

Good luck on your exam. Hope you did well. 🙂

[@flickbaitvrc173]

@@MichelvanBiezen thank you so much professor. Some questions on the exams are exactly the same as the examples you did in videos. I flies through that exam and def got 90 plus. Thank you for the awesome videos!!!!!

[@MichelvanBiezen]

Wow that is great! Good job!
