The coercivity of a bar magnet is 120A//m . It is to be demagnetised by placing it inside a solenoid of length 120cm and number of turns 72. The current (in A) flowing through the solenoid is:

Find the magnetic intensity H at the centre of a long solenoid having n turns per unit length and carrying a current i (a) when no material is kept in it and (b) when a long copper rod is inserted in the solenoid.

Through a long solenoid of diameter 4.1 cm, having 100 turns per cm, a current I = 1A is flowing. At its centre, a 60 turns closely packed coil of diameter 3.1 cm si placed such that the coil is coaxial with the long solenoid. The current in the solenoid is reduced to zero at a steady rate in 10 ms. What is the magnitude of emf induced in the coil while the current in the solenoid is changing?
