Two thin concentric wires shpaed as ...

Two thin concentric wires shpaed as circles with radii `a` and `b` lie in the same plane. Allowing for `a lt lt b`, find:
(a) their mutual inductane,
(b) the magnetic flux through the surface enclosed by the outside wire, when the inside wire carries a current `I`.

Text Solution

Verified by Experts

The correct Answer is:
`(mu_(0)pia^(2))/(2b); (b) (mu_(0)pi a^(2)I)/(2b)`
