A Solenoid coil hsa 50 turns per cm along its length and a cross sectional area of 4 cm sq.200 turns of another wire is wound around the first coil co axialy.The 2 coils are ekectriclly insulated from each other.Calculate mutual inductance between them?
Solenoid 1:
Number of turns per unit length, n1 = 5000 turns/m
Area of cross section, A1 = 0.0004 m2
Solenoid 2:
Total number of turns = n2l = 200
Mutual inductance, M = μon1n2Al = 5.02 x 10-4H
