How can a permanent magnet make the light bulb glow

A permanent magnet can make a light bulb glow by making it move as to convert kinetic and magnetic energy into electric current. Both energy combined in a coil of copper wire causes the electrons in the wire to move then create an electric current and make the light bulb glow. 

Moreover, this process is called electromagnetic induction where there is a creation of potential difference or voltage through an electric conductor, such as coil of wire, when it is exposed to a varying or moving magnetic field.  As long as the conductor is part of a closed circuit, current will flow through it whenever it crosses lines of force in the magnetic field. The faster the magnet or coil moves, the greater the amount of electric current is produced. If more turns were added to the coil or a stronger magnet were used, this would produce more current too.
