A non planar closed loop of arbitrary shape carryign a current I is placed in uniform magnetic field. The force acting on the loop

is zero only for one orientation of loop in magnetic field

is zero for two symmetricaly located positions of loop in magnetic field

is zero for all orientations

is never zero

Text Solution

Verified by Experts

The correct Answer is:
