Picture of Electromagnetic Highlighter

I took a physics class that focused on electromagnetism. It got me really interested in electronics and their relationship to magnetism. This project came from that interest, and now I made this Instructable to show how to make a simple electromagnet housed in a highlighter.

Step 1: Materials and Tools

The first step is to gather everything you'll need. I suggest a quick trip to Radio Shack. They have pretty much all the inside parts needed for this project.

MATERIALS:
-Wire
-Enamel coated magnet wire
-Electrical tape
-AA battery
-Nail (or other small magnetic rod)
-Momentary switch
-Highlighter (of course)

TOOLS:
-Hot glue gun
-Wire cutters
-Soldering iron and solder
-Pliers
-Sandpaper or a file
-Dremel or similar tool (optional)
