There is a solenoid (infinitely long) that is filled with a ferromagnetic material. The magnitization, N is uniform and is parallel to the axis of the solenoid. Made out of a nonmagnetized material there is a conducting oval loop. I put the loop around the solenoid. Find the mutual inductance of the solenoid and the loop. I remove the magnetic core. Find the mutual inductance of the solenoid and the loop.

Solutions

Expert Solution

we took A1 as the area of inner coil. We always take the common area( inner area) of both the coils, for finding the mutual inductance of any coil.

Here the material is the ferromagnetic substance.

U please note that , mutual inductance of a coil is independent of magnetic filed and magnetization, and current flowing.

n1 and n2 be the number of turns per unit length of each coil
