A model of the simplest form of DC electric motor, having two-pole armature wound with enameled copper wire and a permanent magnetic field provided by a removable bar magnet. A disc-type commutator is incorporated and external connection to the ..

A versatile generator that is ideal for powering equipment in the lab. Output 1 Hz to 100 KHz in five ranges with multiplier X10. Wave shape outputs include sine, square, and triangular. Operates on 120V/240V AC using voltage selector.

An excellent activity model for study of generation of electric current. Produces AC/DC current simultaneously when the hand wheel is turned. The generation of AC/DC voltage is represented by bulb holders. Activity guide included. Grade 7-12.

Barlow’s Wheel, invented by an English mathematician in 1822, is a type of electric motor that demonstrates the relationship between electricity and magnetism. As electrons enter the system, eddy currents are attracted to powerful neodymium magnet..
