"PARKWAY PLASTICS, INC."

An excellent set of materials for demonstrating electromagnetism and induced currents, the set includes two electromagnetic coils mounted on plastic saddle blocks, round and square iron cores, split round iron cores, a double core, and a card for showing lines of force. Set of two.

A set of eight coils wound on individual plastic spools. Each coil has two binding posts.

The award-winning Snap Circuit Series uses building blocks with snaps to build electrical and electronic circuit projects.

The Primary and Secondary Coils are ideal for student experiments on transformer effects.

Obtain quantitative data for electrostatic experiments

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.

Quality Lamp Receptacle.

For your Electrostatic Needs!

A bare copper wire of the highest quality. Available in several standard AWG sizes.

A high quality enameled, copper magnet wire.

A good quality bare iron wire. AWG 20.

Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).

The durable Wilmshurst Machine is made for years of use.

Reliable kit in a quality carrying case!

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.
