A current carrying loop is placed in the non-uniform magnetic field whose variation in space is shown in fig. Direction of magnetic field is into the plane of paper. The magnetic of paper. The magnetic force experienced by the loop is

Options

A. Non-zero
B. Zero
C. Cant't say anything
D. None of these

Answer

B

Explanation

Each and every pair of loop elements located symmetrically w.r.t central line experiences zero net force. So total magnetic force experienced by loop is zero.
