How to Light a Lightbulb With a Magnet and Copper Wire

This fun science experiment is easy to do and doesn’t require any special equipment. So, if you are looking for a fun way to spend an afternoon, then be sure to try this experiment!

Required Materials

  • 1x Strong Magnet
  • 1x Spool of Copper Wire
  • Scissors
  • Electrical Tape
  • Soldering Iron and Solder

A Step by Step Guide on How to Light a Lightbulb With a Magnet and Copper Wire

Step 1:

Cut a 5-inch length of copper wire, and remove the insulation. Use the scissors to cut into one side at an angle. If you are using electrical tape instead of solder, wrap your newly exposed wire around the tip of your soldering iron for 1 minute.

Cut the Wire by Size

Step 2:

If you want your circuit to last forever, you should cut another 4 inches of insulated copper wire, twist it tightly with the first 5 inches, and solder them together. This will prevent electricity from escaping from your circuit over time.

Step 3:

Cut another ½ inch off of your spool and remove the insulation. You can do this by using scissors, inserting the wire between some layers of paper and tearing it out, or using a knife to cut through one side. This piece should be approximately 4 inches long.

Step 4:

Strip the insulation from both ends of this piece. Use method one if you have electrical tape; otherwise, use method 2 for bare copper wire. Depending on the wire, you may need to strip off more or less insulation; however, we recommend stripping ¼ inch if possible, or enough, so the two pieces fit nicely together without any exposed copper touching and shorting them. Repeat Step 1 (Remove the insulation from 5-inch wire), except only half as long (2.5 inches).

Strip the Insulation

Step 5:

Begin building your circuit. First, attach one end of the shorter wire to one end by twisting it around and wrapping it tightly with electrical tape. How you do this is up to you; we recommend using a Binder Clip and taping over and under its arm, until it is secure to your satisfaction. Of course, how tight or loose this connection should be will depend on how strong a magnet you have available, so experiment!

If you do everything correctly, no electricity should flow through the connection between the magnet and the copper wire. This is because copper typically does not conduct electricity at all, unless an outside force is applied. This means that electricity would have to flow through the wire to reach the magnet, but without the tape, this connection could never happen. Therefore, this step is crucial in how to light a lightbulb with a magnet and copper wire.

Step 6:

The next step is to attach your small piece of wire to one end of your coil. You can do this by twisting it around and taping it over/under the coil tightly until it is secure, or by wrapping it around a Binder Clip. If electricity can flow through this connection, you should use electrical tape. How tight or loose this connection should be depends on how strong a magnet you have available. Experiment to see what works best.

You need to wrap the wire around the coil’s base the same number of times as the number you want your magnet to produce. The connection should be tight or loose depending on how strong a magnet you have.

If everything goes right, no electricity should flow through this connection unless insulation is stripped off of one or both pieces of wire because copper does not typically conduct electricity at all unless an outside force is applied.

Step 7:

If you do not use solder, attach your battery holder securely with electrical tape to your completed circuit in any manner that it can stay on. How you do this is up to you; if using tape, try touching both ends together before trying anything else! How tight or loose this connection should be will depend on how strong a magnet you have available. If everything goes right, no electricity should flow through your circuit unless insulation is stripped off of one or both pieces of wire between the battery and magnet because copper does not typically conduct electricity at all unless an outside force is applied (electricity must flow through the wire to reach the magnet).

Step 8:

If using solder, attach your battery holder securely with solder to your completed circuit in any manner that it can stay on. How you do this is up to you; however, we recommend soldering as much as possible to make this as sturdy as possible. How tight or loose this connection should be will depend on how strong a magnet you have available, so experiment! Likewise, how many times you wrap your coil with the battery holder wire depends on how many turns you want your magnet to produce, depending on how strong a magnet you have available.

 Attach Your Battery to Solder

How many times you wrap your coil with the battery holder wire should equal this number. If everything goes right, no electricity should flow through your circuit unless insulation is stripped off of one or both pieces of wire between the battery and magnet because copper does not typically conduct electricity at all unless an outside force is applied (electricity must flow through the wire to reach the magnet).
