Posted by abdul rahman on Saturday, April 6, 2013 at 3:21pm.

A rectangular wire loop of dimensions ab, with a=3.5 cm and b=4.5 cm, is pulled parallel to side a at a constant speed v=4.3 m/sec into a region where the magnetic field, |B|=0.125 T, is uniform and perpendicular to the loop. The loop enters the magnetic field at time t=0.

(a) Calculate the rate at which the magnetic flux through the loop is changing. Express your answer in Tesla m2/sec.

(b) What is the magnitude of the induced EMF at time t?
