Question

In the figure below, a region with a constant magnetic field equal to 0.28 T into the page is shown. A single turn, rectangular loop of wire moves into this region with a speed of 17.5 m/s. The dimensions of the loop are a=0.76 m and b=0.5 m. The loop has a resistance of 2.33 .

While the loop is moving into the region of constant magnetic field, the magnitude of the induced EMF is?

While the loop is moving into the region of constant magnetic field, the magnitude of the magnetic force acting on the loop is?

Explanation / Answer

induced emf = e = B*v*l

l = 0.76 m

B = 0.28 T

v = 17.5 m/s

e = 3.724 V

part b )

F = BIL

I = e/R

F = B*e*L/R = 0.34 N
