Introduction: How to Make an Electromagnet
Hello! This is my first instructable. I'm going to show you how to build an electromagnet.
- Magnet wire (aka enamel coated wire) of ~20 gauge
- Alligator clips
- A screwdriver or other iron object (a screw)
- A knife
- A battery (I used a 9-volt)
- A battery holder/clip for your battery
Step 1: Wrap the Magnet Wire Around the Screwdriver
Tightly wind the magnet wire around the screwdriver. Make sure you wind it in the same direction throughout, or it will mess up the polarity of the magnet. Keep some wire sticking out. These wires will be where you hook it up to the battery.
Step 2: Strip the Ends of the Wire
Use a knife to strip the ends of the wire. Be careful not to cut the wire, and more importantly, yourself.
Step 3: Clip the Battery to the Battery Snap
This step is self explanatory.
Step 4: Attach the Alligator Clips
Attach the alligator clips to the battery snap wires and the stripped ends of the magnet wire.
Step 5: Finished!
You're finished! Now find something to pick up with it!
We have a be nice policy.
