Magnet Visualizer Demo Set

A teaching tool to help beginners understand magnetic flux by observing the effect of the firld created by bar magnets or by a live conductor. The PP-7 demonstrator is particularly effective because it shows the effects of magnetic fields in three dimension. The clear acrylic tank contains iron fillings in a paraffin suspension medium. Through the middle of the tank is a hole in which small, alnico magnets or wires may be threaded to demonstrate a number of magnetic effects.
