Find the mutual inductance of two concen...

Find the mutual inductance of two concentric coils of radii `a_(1)` and `a_(2)(a_(1) lt lt a_(2))` if the planes of the coils are same.

Text Solution

Verified by Experts

Let a current I flow in coil of radius `a_(2)`.
Magnetic field at the centre of coil `=(mu_(0)i)/(2a_(2))pia_(1)^(2)`
`or Mi=(mu_(0)i)/(2a_(2))pia_(1)^(2) or M=(mu_(0)pia_(1)^(2))/(2a_(2))`
