This box changes resistances in a laboratory circuit.

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

With emphasis on ease and accuracy, this capacitor board demonstration teaches students about series and parallel circuit connections.

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

A good quality bare iron wire. AWG 20.

Flexible, Insulated Wire.

A high quality enameled, copper magnet wire.

Flexible, 18 gauge wire with alligator clips at both ends. The clips have a protective vinyl sheath.

Economical yet Sturdy

Investigating Inductance has never been this easy

Bring older, weaker magnets back to life with this magnetizer.

Closed Case Form Electroscope is enclosed, preventing air currents from affecting the deflection of the leaves.

The Economy Magnet Kit showcases the basics of magnetism.

Electrostatic charges are indicated by the deflection of a black plastic straw pivoted on a pin. The polished zinc plate on top is used to demonstrate photoelectric effect and various other electrostatic demonstrations. The metal case measures 14 cm in diameter. The scale is graduated in 10° increments in two quadrants.

Grab and hold students' attention with these interactive and affordable demonstrations that show core physics concepts in action.
