How could you use a magnet to make the bulb light up?

Answer 1

This may take quite a bit of effort, as most incandescent light bulbs use a fair bit of current. Find the smallest bulb with the lowest operating voltage, from a small flashlight.

Get as many turns as you can from your piece of wire, wrapping it around and around.

Connect the bulb across the ends of the wire. One end goes to the centre contact and the other to the side of the bulb. (assuming a small Edison screw type bulb.)

Now move the magnet rapidly inside the coil you made with the wire.

The lamp will only blink during the movement of the magnet.

By rapidly moving the magnet back and forth, you can generate an almost continuous supply of AC current and keep the bulb alight.

Answer 2

To make a light bulb light connect it to a coil of wire and then take a permanent magnet and wave it by the coil of wire. The flux from the magnet will cut the coil of wires and induce a current to flow in the wire. The bulb should glow each time the magnet passes the coil.

Answer 3

You can pass an electric current through a coil of wire using a magnet to induce a flow of electricity. This principle is known as electromagnetic induction and is commonly used in devices like generators to produce electricity. By moving a magnet near a coil of wire connected to a light bulb, you could generate enough electricity to make the bulb light up.

Answer 4

no but copper wires in liqued nitrogen can work

Answer 5

A moving magnetic field causes an electric current to flow in a copper wire. This current will light a bulb.
