Question

What is the formula for mutual inductance ?

Answer 1

Answer:

hey mate here is ur answer

Mutual Inductance formula:

Now, if em = 1 and dI1 / dt = 1, then on substituting the value in the given equations, we see that the value of M, that is mutual inductance is 1 Henry.

Answer 2

Answer:

Because of this, we can write the mutual inductance between the two coils as: M12 = M21 = M. By cross multiplying the two equations above, the mutual inductance, M that exists between the two coils can be expressed in terms of the self inductance of each coil.
