A very small circular loop of radius `a` is initially coplanar & concentric with a much larger circular loop of radius `b( lt lt a)`.A constant current `I` is passed in the large loop which is kept fixed in space & the small loop is rotated with constant angular velocity `omega` about a diameter.The resistance of the small loop is `R` & its inductance is negligible The induced `emf` in the large loop due to current induced in smaller loop as a function of time is equal to `1/x((pia^(2)mu_(0)omega)/b)^(2) (I cos 2omegat)/R`.Find out value of `x`.
