Consider two circular coils of radii a and b, number of turns N1 and N2 respectively, both centered at the origin and located on the same plane. If the larger coil carries an alternating current I(t) = Io cos(wt), find the induced EMF in the small coil. You many assume the radius of the smaller coil b« a so that B due to the larger coil is constant across its surface and equal to the value at the center. N1 26 : O I N2
