Activités d'électricité/de magnétisme

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

Demonstrates operation of 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.

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.

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.

Demonstrates mechanical to electrical energy conversion without batteries.

Handheld generator producing static electricity through friction, ideal for classroom experiments.​

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.

Uses conductive play dough and insulating play dough to teach electrical circuits basics in a fun, hands-on way.

For your Electrostatic Needs!

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.
