In the figure, a conducting rod of length L = 31.0 cmmoves in a magnetic field B

Question

In the figure, a conducting rod of length L = 31.0 cmmoves in a magnetic field B  of magnitude 0.540 Tdirected into the plane of the figure. The rod moves with speed v = 6.00 m/s in the direction shown

Part A

When the charges in the rod are in equilibrium, what is the magnitude E of the electric field within the rod?

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

E=

Part B

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.

Part C

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

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

E =

Explanation / Answer

A) electric field =v*B =6*0.54=3.24 V/m

B) Vba =BVL =0.54*6*0.31=1.0044 V

C) motional emf induced in the rod=BVL =0.54*6*0.31=1.0044 V
