Question

A magnet of magnetic moment m is rotated through 360 degree in a magnetic field b, the work done will be

Answer 1

above is your answer.

Answer 2

Dear Student,

◆ Answer -

Work done will be 0 J.

● Explanation -

The work done by magnetic field is given by following formula -

W = -m × b × (cosθf - cosθi)

W = -mb × (cos360° - cos0°)

W = -mb × (1 - 1)

W = -mb × 0

W = 0 J

Hence, the work done will be 0 J.

Thanks dear. Hope this is helpful to you...
