Subject: Torque due to magnetic field on a circular loop

Hi,

I was reading about the torque due to a magnetic field on a loop and the 
article was explaining it on a rectangular loop. The field was to the east and 
the torque turned the loop in the z axis.

Now, what if our loop was a circular loop? what would happen? A rectangular 
loop is easy since there is only 1 net torque due to the 2 forces that don't 
have the same line of action, but what about a circle?

Thanks
