Q. 9

The mutual induct A. increases when they are brought nearer.

B. depends on the current passing through the coils.

C. increases when one of them is rotated about an axis.

D. is the same as M21 of coil 2 with respect to coil 1.

Answer :

As we know that the formula of mutual inductance is given by in this is the area of cross-section of coil which is common and l is also common length and n1 and n2 are the no. of turns in the coils.

So option (a) is correct and option (d) is also correct. In above formula we can see that current is independent and also angle has no meaning hence options (b) & (c) are wrong.

Therefore, options (a) & (d) are the correct.
