Instructions / Notes:
- A solenoid is wound through a piece of plexiglass for use with iron filings on an overhead projector.
- Iron filings are sprinkled on the plexiglass surface and the random orientation should be noted.
- The power supply provides only an impulse current to the solenoid.
- One or two pulses of current will reorient the iron filings.
- The filings will reorient into lines where the magnetic field lines are strongest.
