Question

± Motional EMF in a Conducting Rod with the magnetic field. Note that once the charges are in equilibrium, no force is required to keep the rod moving with constant velocity In the figure, a conducting rod with length L 30.0 cm moves in a magnetic field B of magnitude 0.500 T directed into the plane of the figure. The rod moves with speed v 6.00 m/s in the direction shown. (Fiqure 1) Part E 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 Hints -696 ba Submit My Answers Give Up Incorrect, Iry Again, 5 attempts remaining Part F Figure 1 of 1 What is the magnitude & of the motional emf induced in the rod? Express your answer in volts to at least three significant figures Hints ao 1.696V Submit My Answers Give Up Incorrect, Iry Again, 6 attempts remaining Continue

Explanation / Answer

Emf induce in the rod

E = BLV = 0.5*0.30*6 = 0.90 volt PART (F)

potential difference across the rod

Vab = Electric field * length = VB* L = 0.90 volt PART (E)
