A conducting square loop initially lies in the X Z plane with its lower edge hinged along the X -axis. Only in the region y 0 , there is a time dependent magnetic field pointing along the Z -direction, B (t)=B₀( t) K , where B₀ is a constant. The magnetic field is zero everywhere else. At time t=0 , the loop starts rotating with constant angular speed about the X axis in the clockwise direction as viewed from the +X
