Question

Krishna J · Accepted Answer

Step 1: Calculate the work done using the formula W = 1/2 * M * B * (1 - cosθ), where M = 10 A m

Question

A bar magnet for dipole moment 10? JT–1 is free to rotate around a horizontal plane. A horizontal magnetic field 4×10–5 T exists on the space. The work done in rotating the magnet slowly from a direction parallel to the field to a direction 60° from the field will be?
