Question

Calculate the mutual inductance between two coils if a current 10 A in the primary coil changes the flux by 500 Wb per turn in the secondary coil of 200 turns.

(a) 10 H

(b) 10^4 H

(c) 1000 H

(d) 100 H

The question was posed to me in homework.

I'd like to ask this question from Electromagnetic Inductance topic in section Electromagnetic Induction of Physics – Class 12

Answer 1

Right option is (b) 10^4 H

For explanation I would say: NΦ = MI

200 × 500 = M × 10

M = 10^4 H
