Question

A magnetic needle kept non parallel to the magnetic field in a non uniform magnetic field experience.

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

Answer 1

The correct option is C Both a force and a torque

Magnetic needle can be considered as a magnetic dipole since it is placed in a non uniform magnetic field it will experience af force as magnetic force on both magnetic force will be different. Also, needle is placed non parallel to the field, so it will experience a torque also.

Therefore, C is correct option.
