Faraday’s Law and Induced EMF
The figure displays a rectangular loop of wire with sides x and
y placed in a region where a uniform magnetic field ! exists. The
resistance of the loop is R. Initially the field is perpendicular
to the plane of the loop and is directed out of the page. The loop
can rotate about either the vertical or horizontal axis, passing
through the midpoints of the opposite sides, as shown.
