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?

Rod on Rails Two The conducting rod shown in Fig. 31-42 has alength L and is being pulled along horizontal, frictionless,conducting rails at a constant velocity v. The rails are connectedat one end with a metal strip. A uniform magnetic field , directedout of the page, fills the region in which the rod moves. Assumethat L = 17 cm, v = 6.4 m/s, and B = 1.0 T.

A conducting rod of length l is rotated in a uniform magnetic field of induction B with an angular velocity with its plane perpendicular to the field.  Then the emf induced between its two ends of the rod is?

 

 

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?
