Question
A rectangular loop of wire is moving toward the bottom of the page with a speed of 0.019 m/s (see the drawing). The loop is leaving a region in which a 2.3 T magnetic field exists; the magnetic field outside this region is zero. During a time of 3.0 s, what is the magnitude of the change in the magnetic flux?

The loop is leaving a region in which a 2.3 T magnetic field exists; the magnetic field outside this region is zero. During a time of 3.0 s, what is the magnitude of the change in the magnetic flux?Explanation / Answer
chnage in manetic flux = A*dB
= length*breadth*dB
= 0.019*3*0.08*2.3
= 1.05*10^-2 T.m^2
