Over a solenoid of 50 cm length and 2 cm radius having 500 turns. Is wound another wire of 50 turns near the centre. Calculate mutual inductance of the two coils. If currents in primary changes From 0 to 5 a in 0.02 s, what is the emf induced in secondary coil ?

Over a solenoid of 50cm length and 2cm radius and having 500turns is would another wire of 50 turns near the centre. Calculate (i) mutual inductance of the two coils (ii) Induced emf in the second coil when the current in the primary changes from 0 to 5A in 0.02 sec.

The mutual inductance of a pair of a coil is 0.75 H. if the current in primary coil changes from 0.5 A to 0A in 0.01 s. the average induced emf in secondary coil is

Calculate the mutual inductance between two coils when a current 2A changes to 6A in and 0.2 s and induces an emf of 20mV in secondary coil.

Calculate the mutual inductance between two coils when a current 2A changes to 6A in and 0.2 s and induces an emf of 20mV in secondary coil.

Calculate the mutual inductance between two coils, when a current of 4.0 A changes to 8.0 A in 0.5 s and induces an e.m.f. of 50 mV in the secondary coil.

The mutual inductance of a pair of coils is 0.75H. If the current in the primary coil changes from 0.5A to zero in 0.01s, find the average induced e.m.f. in the secondary.
