1. The problem statement, all variables and given/known data 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? 2. Relevant equations torque=(magnetic field)(area)(current) 3. 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.
