A current carrying loop is placed in a uniform magnetic field. The torque acting on the loop does not depend upon (a) area of loop (b) number of turns in the loop (c) shape of the loop (d) strength of the magnetic field

Answer: (c). τ = nIABsin θ. It depends on area, turns and field, but not on the shape of the loop for a given area. So the answer is (c) shape of the loop.

Current Loop as a Magnetic Dipole

A current carrying loop is placed in a uniform magnetic field. The torque acting on the loop does not depend upon

Show answer and solution

Answer: (c)

$\tau = nIAB\sin\theta$ .
It depends on area, turns and field, but not on the shape of the loop for a given area.
So the answer is (c) shape of the loop.
