1. The problem statement, all variables and given/known data

Here is the problem:

Given a rod of Length L with one end centered at the origin and the other at y=L and given a magnetic field of strength B that points out of the page, what is the graph of the magnitude of the voltage read by a voltmeter as a constant velocity is applied to the rod as it moves across the field?



2. Relevant equations

E_y, Induced = -v *B (electric field induced)
EMF = -v*B*L



3. The attempt at a solution


I am having trouble visualizing the specifics of the motion, if it is a constant velocity should i expect a constant slope for the graph of the voltage with traits similiar to X=Y or is it simply a constant value? (which seems unreasonable)

Can't you use this equation to derive the answer? ;-).

"EMF(voltage) = -v*B*L"
