A solenoid 0.70 m in length and of 2100 turns has a radius `4.5xx10^(-2) `m. A second coil of 750 turns is wound over the middle part of the solenoid. Find the self inductance of the solenoid and mutual inductance between the two coils.

What is the mutual inductance of coil and solenid if a has a radius 4 cm and coil of 700 turns is would on the middle part of the solenoid ?

If the number of turns per units length of a coils of solenoid is doubled , the self- inductance of the soleniod will

If the number of turns per units length of a coils of solenoid is doubled , the self- inductance of the soleniod will

A solenoid having 500 turns and length 2 m has radius of 2 cm , the self inductance of solenoid

The current in a long solenoid of radius R and having n turns per unit length is given by i= i_0 sin omega t . A coil having N turns is wound around it near the centre. Find (a) the induced emf in the coil and (b) the mutual inductance between the solenoid and the coil.
