Question

A. When the charges in the rod are in equilibrium, what is the magnitude E of the electric field within the rod? B. What is the magnitude Vba of the potential difference between the ends of the rod? C. What is the magnitude £ of the motional emf induces in the rod? Please express answers in volts to at least three sig fig. Thanks Motional EMF in a Conducting Rod Constants In the figure, a conducting rod of length L-27.0 cm moves in a magnetic field B of magnitude 0.370 T directed into the plane of the figure. The rod moves with speed v 7.00 m/s in the direction shown. (Figure 1) Figure 1 of 1

Explanation / Answer

a)

Magnitude of electric field

E=vB =7*0.37

E=2.59 V/m

b)

the magnitude Vba of the potential difference between the ends of the rod

Vba=EL=2.59*0.27 =0.6993 Volts

c)

the magnitude £ of the motional emf induces in the rod

E=Vba =0.6993 Volts
