A closely wound solenoid of 800 turns and area of cross-section 2.5 xx 10^-4 m^2 carries a current of 3.0 A. Explain the sense in which the solenoid acts like a bar magnet. What is its assosciated magnetic moment?

A long solenoid has 200 turns per cm and carries a current i. The magnetic field at its centre is 6.28xx10^(-2)Wb//m^(2) . Another long solenoid has 100 turns per cm and it carries a current i/3. The value of the magnetic fieldat its centre is

A long solenoid with 15 turns per cm has a small loop of area 2.0 cm^2 placed inside the solenoid normal to its axis. If the current carried by the solenoid changes steadily from 2.0 A to 4.0 A in 0.1 s, what is the induced emf in the loop while the current is changing?
