How does electromagnetic induction produce a current?

When a wire moves through a magnetic field the wire cuts through the magnetic field lines. This cutting through gives a force on the electrons in the wire, pushing them along, and these moving electrons are the current in the wire. The faster the wire moves, or the stronger the field, the more the electrons are pushed and the greater the current.
