The correct response is: **The current increases as the magnet's movement increases.**
This is because moving a magnet in and out of a coil of wire generates a change in the magnetic field within the coil, which induces an electric current according to Faraday's law of electromagnetic induction. The faster the magnet is moved, the greater the change in magnetic field and the stronger the induced current.
