PURPOSE: Show the magnetic fields of parallel and antiparallel current-carrying wires.
DESCRIPTION: Special overhead projector projectuals have been constructed for parallel and antiparallel wires. The difference between the magnetic fields in these two cases can easily be seen.
SUGGESTIONS:
REFERENCES: (PIRA 5H15.20, 5H15.25)
EQUIPMENT: Parallel and antiparallel wire arrangements on projectuals, power supply, and overhead projector.
SETUP TIME: None.
