Passing a copper wire coil through a magnetic field influences another coil to also sway. It is with this demonstration that you can teach your physical science fans about electromagnetism. Note that the assembly requires about an hour, while the demonstration you can do with it is finished within 15 minutes. Once you have constructed it, however, you can store it for repeated use in other class periods or subsequent school years.
