A conductor of known volume (V) passes a uniform magnetic field(B)with a constant velocity (v) the conductor is a source of induced EMF, a power source to a circuit. The induced EMF can be calculated via formula: ϵ=−vBL A diagram of this:
The conductor has resitance(R) and induces current equal to:
I=VR Excluding all other factors that would retard the motion, what would happen if the magnetic field span is reduced? Span; meaning It covers a smaller volume(i.e area) of the conductor at the same magnetic field strength as before, moving at the same velocity:
From the motional EMF formula, if all the vairbales are the same (v,B,L) it should induce the same ϵ. The only difference is the induced current correct? How would I go about calculating it?
EDIT: There is a connection to the conductor via an exterior circuit from the top and bottom, complete connections(not partial) but fully connects the top surface and bottom.
