What would happen if you moved the wire from north to the south pole?

Flemings right hand rule requires that the wire is moved at a 90° to the magnetic field so it can not be used if you move the wire from the north to the south pole.

You can't use Flemings right hand rule if the wire is moved in the same direction as the magnetic field.

This is because if the wire is moved in this direction no magnetic field lines are crossed and therefore no current is induced in the wire so nothing happens.
