A solenoid made up of copper wire consists of 400 turns and carries a current of 5 A. If length of the solenoid is 0.5 m and has a radius of 2 cm, find the magnitude of the magnetic field inside the solenoid.

A solenoid 60cm long and of radius 4*0cm has 3 layers of windings of 300 turns each. A 2*0cm long wire of mass 2*5g lies inside the solenoid (near its centre) normal to the 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 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 windings of the solenoid can support the weight of the wire? g=9*8ms^-2 .
