what is the magnitude e of the motional emf induced in the rod?
A conducting rod with length L = 31.0 cm moves in a magnetic field B of magnitude 0.460 T directed into the plane. The rod moves with speed v = 6.00 m/s. what is the magnitude e of the motional emf induced in the rod?
A conducting rod is moving through a magnetic field, as in the drawing. The magnetic field strength is 0.65 T, and the speed of the rod is 5.6 m/s. Suddenly, the field strength decreases to 0.48 T. To what value must the speed v of the rod be adjusted to reestablish the emf induced between the ends of the rod at its initial value?
