Fun Project with the Kids

Here is a fun little project to do with kids.  It is also educational.  This was done a few years ago, but we still have fun with it from time to time.  This is a simple electro-magnet built by winding some copper wire around a steel screw, and connecting it to an electrical current (low voltage provided by some "AA" batteries) via an on/off switch.  I stuck a little LED in there to show when it was turned on, not that it was needed with a switch that was labeled, but it was fun.

My Parts List:

  • 1 x Project Box
  • 1 x 6' of copper wire
  • 1 x Screw
  • 1 x SPST switch
  • 1 x LED (with resistor built in)
  • 1 x power connecter (really not needed, batteries could be inside of project box)

Time to Completion:

  • About four hours with the "help" from the kids.  ;-)

Here is a pic:

Just a fun little project.  I'll work on getting some pictures of it in use.
