"The Mystery of Lyle and Louise"

Demonstrates operation of motors and generators.

Students use the St. Louis Demo Motor to research fundamental principles of electric motors and generators.

Demonstrate the relationship between magnetic field and current.

Demonstrate the transfer of mechanical energy into electrical energy with a simple motion of your hand.

Glows with Characteristic Brilliance!

Demonstrate magnetic fields on your desk or overhead with this clear container of iron fillings. Using magnets, you can show students how the fillings move and cluster together.

Pith balls are an electrostatic necessity.

Demonstrate the conversion of mechanical energy into electrical energy by generating a static charge.

Ideal electrostatic tool for generating voltages.

Pieces of reusable zinc-plated iron wire for magnetic field experiments.
