"The Mystery of Lyle and Louise"

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

Magnetic wand, Use this wand with our magnetic marbles or other magnetized items or pick up those paper clips you just dropped. It has many uses and is fun to watch in action.

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

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.

For your Electrostatic Needs!

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

A thin aluminum coating produces great sensitivity to electrostatic charges. Styrofoam pith-like balls measure 8 mm in diameter and each has a silk suspension cord.

Pith balls are an electrostatic necessity.

Good for magnetic experiments. Not so good with coffee.

Glows with Characteristic Brilliance!

Ideal electrostatic tool for generating voltages.

Demonstrates operation of motors and generators.

Demonstrate the relationship between magnetic field and current.

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