Question

The torque experienced by a magnetic dipole placed in a magnetic field is:

Options

• \[\vec{\tau} = \vec{m} \cdot \vec{B}\]

• \[\vec{\tau} = \vec{m} \times \vec{B}\]

• \[\vec{\tau} = -\vec{m} \cdot \vec{B}\]

• \[\vec{\tau} = \vec{p} \times \vec{B}\]

Answer 1

A magnetic dipole in a magnetic field experiences a torque \(\vec{\tau} = \vec{m} \times \vec{B}\), directly analogous to the electric dipole torque \(\vec{\tau} = \vec{p} \times \vec{E}\).
