Problem-1
A square conducting loop of sides d = 25 cm is located in a peak ac magnetic field of Hm = 1 A/m varying at a frequency f = 5 MHz. Description: 18493.png is perpendicular to the plane of the loop. What voltage will be read on a voltmeter connected in series with one side of the loop?
Solution
Since the loop is stationary, and the area is time dependent, the transformer emf is induced. The emf induced is given as,
