Motional Units

Here is a sanity check for the formula used above: it is good to remind ourselves that an emf is just a voltage, so it must also have the unit of electric potential, or voltage. If you recall that potential is just potential energy per unit charge, we can figure out that a volt is the same as one joule per coulomb. Watch this video to see how this unit arises from the formula for the motional emf in terms of the magnetic field.
