A very small circular loop of area `5xx10^(-4)m^(2)` , resistance `2Omega` and negligible inductance is initially coplanar and concentric with a much larger fixed circular loop of radius `0.1m` . A constant current of `1A` is passed in the bigger loop and the smaller loop is rotated with angular velocity `omega rad//sec` about a diameter. Calculate (a) the flux linked with the smaller loop, (b) induced emf (c) induced current in the smaller loop, as a function of time. |
