The magnetic potential energy, when a magnetic bar of magnetic moment $m$ is placed perpendicular to the magnetic field $B$ isNEET 2024 (Re-NEET)

Options:

Answer:

Solution:

Potential energy stored in external magnetic field is given by $U = - m \cdot B$ $∵$ Angle between $m$ and $B$ is $9 0^{\circ}$ $∴ U = - m B cos 9 0^{\circ}$ $= 0$
