A magnetic needle facing north-south can roatate freely in a horizontal plane. A conducting wire is placed parallel to it along north-south direction.

A

Direction of current is from south to north and the conductor is above the magnet-north pole of the magnet will be deflected towards west.

B

Direction of current is from north to south, the conductor is above the magnet-south pole of the magnet will be deflected towards west.

C

Direction of current is from south to north, the conductor is below the magnet-south pole of the magnet will be deflected towards west.

D

Direction of currnet is from north to south, the conductor is below the magnet-the north pole of the magnet will be deflected towards west.

A 60 cm long solenoid of radius 4.0 cm has 3 layers of windings of 300 turns each. A.2.0 cm long wire of mass 2.5g lies inside the solenoid (near its centre) normal to its axis, both the wire and the axis of the solenoid are in the horizontal plane. the wire is connected through two leads parallel to the axis of the solenoid to an external battery which supplies a current of 6.0A in the wire. What value of current (with appropriate sense of circulation) in the windling of the solenoid can support the weight of the wire ? g=9.8m*s^(-2) .
