Homework Statement
A mutual inductor consists of two coils X and Y arranged so that one quarter of the magnetic flux produced by X links with Y. When X is used as the primary coil and Y as the secondary, the mutual inductance is M. What is the mutual inductance when Y is used as primary coil and X as the secondary?
a. M/4
b. M/2
c. M
d. 2M
e. 4M
Homework Equations
[tex]E=-M\frac{\Delta I}{\Delta t}[/tex]
The Attempt at a Solution
I think the answer is (c) because M is independent whether X or Y is the primary one. Am I right?
Thanks
