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

In this video I will find the torque on a current loop inside a magnetic field.

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?

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 :)

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.

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

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

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

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

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