Figure showns a fixed square frame of wire having a total resistance `r` placed coplanarly with a long staight wire.The wire carries a current `i` given by `i=i_(0)cos (2pil//T)`.Find (a) the flux of the magnetic field through the square frame (b)the `emf` induced in the frame and (c) the heat developed in the frame in the time interval `0` to `10 T`.

Text Solution

Verified by Experts

The correct Answer is:
`(a) phi=(mu_(0)ia)/(2pi)l""n((a+b)/(b)):`
`(b) epsi=(mu_(0)i_(0)a)/(T)l""n((a+b)/(b))sin((2pit)/(T))`
`(c) heat=((5mu_(0)^(2)i_(0)^(2)a^(2))/(Tr))[l""n((a+b)/(b))]^(2)`
