In the figure, a conducting rod of length L = 33.0 cm moves in a magnetic field

Question

In the figure, a conducting rod of length L = 33.0 cm moves in a magnetic field B of magnitude 0.470 T directed into the plane of the figure. The rod moves with speed v = 6.00 m/s in the direction shown.

A. What is the magnitude Vba of the potential difference between the ends of the rod?

Express your answer in volts to at least three significant figures.

(I got 0.7755 and it was wrong)

B.

What is the magnitude E of the motional emf induced in the rod?

Express your answer in volts to at least three significant figures.

Explanation / Answer

A)

Vba = BLv

= 0.47*0.33*6

= 0.931 V

B)

E = Motional emf

= BLv

= 0.47*0.33*6

= 0.931 V
