Magnetic induction: Motional EMF, Faraday`s law, Induced electric
... As we have seen earlier in these notes, the EMF induced by the first method is the motional EMF, ultimately stemming from the Lorentz forces on the electrons in the moving wires. But the physics underlying the other two methods seems to be quite different: Moving a magnet or varying the current thro ...
