Question

if coil 2 is turned 90 so that its axis is vertical,
does the mutual inductance increase or decrease? Explain.

Expert Solution
Step 1

Given: Two current carrying coil having mutual inductance M.

To find: When coil 2 is turned 90° so that axis is vertical then what is effect on mutual inductance.

Solution: 

Mutual inductance formula for two current carrying coil is given by

M=kL1L2                 ........................(1)

Here, M is mutual inductance,

L1 is inductance of first coil,

L2 is inductance of second coil, and

k is coupling factor.
