MCQ
A mgnetic needle is kept in a non-uniform magnetic field. It experiences
- ✓A force and a torque
- BA force but not a torque
- CA torque but not a force
- DNeither a torque nor a force
✓
Answer
Correct option: A.
A force and a torque
a
A magnetic needle is a magnetic dipole.
A magnetic needle is a magnetic dipole.
In a non uniform Magnetic field Force on each of the poles will be different in both magnitude and direction.
Due to difference in Magnitude the dipole experiences a Force,
Due to difference in Direction the dipole experiences a Torque.
