An irregular closed loop carrying a current has a shape such that the entire loop cannot lie in a single plane. If this is placed in a uniform magnetic field, the force acting on the loop (a) must be zero (b) can never be zero (c) may be zero (d) will be zero only for one particular direction of the magnetic field
