Electric Bell

Description

Comprising 1 welding coil of 5 turns on former with insulated handle and short-circuiting pins,1 annular melting trough with insulated handle to show heating by induction,1 jumping ring which is thrown clear when primary current is started and a floating ring which remains freely suspended when primary current is flowing.

Description

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

Description

With this simple electric motor model students can investigate the relationship between voltage supplied to rotor and polarity / position of magnets. On applying 6V DC to 4mm sockets, the rotor will begin to rotate across its vertical axis.

Description

Each plate is fitted with a 4 mm socket terminal.
