Physics?!?!?

Is it possible to orient a current carrying loop of wire in a unifrom magnetic field so that the loop will not tend to rotate?

I say no because the field of the loop always points in the same direction....but it doesnt sound right?! Give me some feedback please!

I'm pretty sure a bit of fiddling with that should show you, if you think about it if it's possible it should be when the plane of the coil is normal to the field...

oh thanks!sry im sick

Yeah I've done several modules in electrodynamics.

 

I will admit not being about to see the animation ()

 

But from your description, it being a uniform B field and a current loop and the description of the animation I assumed it would be of use.

 

I think IIRC

 

The torque = I*A * B * Sin(Theata)

 

So if Sin(Theta) = 0 there is no torque of the current loop

 

Where Theta is the angle between the current and the field.
