A rectangular wire loop (4.0 cm by 5.0 cms) has 0.20 T of external uniform magnetic field falling perpendicular to its plane. The electrical field starts decreasing at constant rate such that at t=2.0 seconds, it disappears completely. Explain why an electric current is being induced in the wire, find its value, and show its direction.

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.

9. FALLING LOOP A rectangular loop is w in width and very long in height. It is held vertical, initially at rest. The loop has internal resistance R. It is in a region of space where there is a uniform magnetic field of strength Bo which is perpendicular to the plane of the loop. The region of space directly below the loop has no magnetic field in it. When the loop is dropped the magnetic flux will change and the...
