Question

a circular coil is placed in uniform magnetic field in the direction out of plane of paper and carrying current in clockwise direstion .the magnetic force will try to.. a.contract the coil b.expand the coil c.move the coil rightward d.rotate the coil

Answer 1

There is a circular coil which is a dipole placed in a non uniform magnetic field due to PQ. Now magnetic field due to circular coil will be out of the plane and not uniform. Therefore, force which will act on PQ will have direction,

F=

dl

×

B

since

dl

is vertically downwards and

B

is out of the plane therefore, direction of

F

will be towards left that is perpendicular to the PQ. or right angled with PQ.

Therefore, option(D)

Answer 2

Answer:

OPTION D , ROTATE THE COIL
