Question

A magnetic needle is kept in a non-uniform magnetic field. It experiences:

• A. neither a force nor a torque
• B. a torque but not a force
• C. a force but not a torque
• D. a force and a torque

Hint:

In a non-uniform magnetic field, the imbalance in forces on the poles of a magnetic dipole generates both a net force and a torque. The torque aligns the dipole with the field lines.
