This motor-generator set gives students an insight into the physical and technical relationships on which electric motors, generators and transformers are based. The modular system allows to set up different function models without tools: Various DC motors Series and shunt motor Synchronous motor DC generator and alternator Transformer.

This set allows the performance of 10 student experiments about the following topics:
Magnetic field of a coil
Conversion of electrical energy into kinetic energy
Commutator
Direct current motor
Synchronous motor
Series and shunt-wound motors
Electromagnetic induction
The electrical generator
Engine-generator
Transformer

Study the concepts of Newton?s and Coulomb?s laws with this apparatus. This apparatus can be used to demonstrate repulsion, attraction of charged bodies and provides the ability to measure the angle between the 2 strings and thus the force between the two charged spheres. The charge can be provided by a Wimshurst machine or a Van de Graff generator or by simply rubbing a plastic rule with on a duster. Includes manual.

For density experiments on solids & liquids, hollow body, upper loading pan, and weighted lower loading pan brass plated.

A wooden base board with one meter scale divided into mm with following accessories : 1. One each White face object and receiving screens each 150 x 100 mm, with aperture, mounted on wooden base with an index mark. 2. Two plane mirrors 150 x 100 mm mounted as above. 3. One lens holder V shaped, wooden. 4. One needle vertically mounted in a short wooden rod, on base. 5. One candle holder on base. The components have the same optical center height.

Comprises a white painted wooden board mounted on nonskid plastic feet, and a removable turntable about 170 mm in diameter. Two orthogonal lines along the turntable’s diameter divide it into four equal quadrants Just beyond the rim of the turntable, a circular scale graduated 90 – 0 – 90 – 0 – 90 °, with 1° subdivision, Also includes a ray box with a 12 V, 24 W bulb Supplied complete with a cylindrical convex lens with focal length approx. 75 mm and two double slits, giving one wide beam slit and one each of single, triple and five slits An optical set is available separately, comprising of one each of rectangular, semi-circular, right-angled triangular – 90 ° 45 ° 45° trapezoidal, biconvex and biconcave prisms.
