Solution

The correct option is A a force and a torque
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.

Q. (i) Derive and expression for axial magnetic field of a bar magnet act as an equivalent solenoid.
(ii) A magnetized needle is a uniform magnetic field experience a torque but no net force. An ion nail near a bar magnet, however experience a force of attraction is addition to a torque. Why?

Q. Assertion :The net magnetic force on a current loop in a uniform magnetic field is zero but torque may or may not be zero. Reason: Torque on a current carrying coil in a magnetic field is given by

¯ τ = n I (¯ A X ¯ B) .

Q. In a uniform electric field, an electric dipole experiences only torque. But when the electric field is non-uniform, it experiences torque as well as a net force. Why is it so?

(A)

: When a magnet is placed in a non-uniform magnetic field , it experiences both translatory and rotatory motion.

Reason

(R)

: The poles of the bar magnet experiences resultant force and torque.
