A: out of the page B: into the page C: to the top of the page D: to the bottom of the page E: to the right F: to the left In the figure below, a region with a constant magnetic field equal to 0.41 T into the page is shown. A single turn, rectangular loop of wire moves into this region with a speed of 14.9 m/s. The dimensions of the loop are a-0.57 m and b 0.31 m. The loop has a resistance of 2.31 . While the loop is moving into the region of constant magnetic field, the direction of the induced magnetic field in the loop is: A: out of the page B: into the page C: to the top of the page .

Explanation / Answer

a)

Out of the page

b)

Induced emf

E=BLv =0.41*14.9*0.57

E=3.482 Volts

c)

Induced current

I=E/R =3.482/2.31=1.5074 A

Magnetic force acting on the loop is

F=BIL =0.41*1.5074*0.57

F=3.523*10-1 N

d)

To the left
