Homework Statement
For a metal coil, if a magnetic field is being applied parallel to each circular loop, why is there torque being exerted on the coil?
Homework Equations
torque=(magnetic field)(area)(current)
The Attempt at a Solution
When I cross the current with the magnetic field, I get a vector pointing down the coil. Isn't this a compression of the coil instead of a rotation? How is there torque?
Thanks for any replies.
