RE-NEET 2024 Physics Magnetic Potential Energy MCQ Question with Solution

The magnetic potential energy, when a magnetic bar of magnetic moment $\vec{m}$ is placed perpendicular to the magnetic field $\vec{B}$ is

A

$\frac{mB}{2}$

B

Zero

C

$-mB$

D

$mB$

Correct Answer

Option B

Detailed Explanation

The potential energy of a magnetic dipole in a magnetic field is given by $U = -\vec{m} \cdot \vec{B}$ . When the dipole is perpendicular to the field, the dot product is zero, hence the potential energy is zero.
