A magnetic dipole is placed in a uniform magnetic field of intensity $B$ , oriented along the direction of the field. If the magnetic dipole moment is $M$ , then the maximum work an external agent can perform in rotating the dipole will be

Options:

Answer:

Solution:

The maximum work done by an external agent is

$W = U_{180 °} - U_{0 °}$

$W = M B - (- M B)$

$W = 2 M B$
