C-Core Coils, Set of 5

A range of sturdy, mounted coils, designed for use with laminated cores and clips. The coils have different numbers of turns of copper wire, allowing students to investigate the relationship between voltage and number of turns, showing how transformers work etc. They can also be used to demonstrate electromagnetic induction (Faraday's law). Coils come complete with 4 mm sockets and include these coils: 50+ 100 turns; 200+ 300 turns; 300+ 350 turns; 400+ 500 turns; 550+ 600 turns.

Demountable Transformer Kit, Standard

A laminated, low loss core on which to attach coils in different combinations to demonstrate the principle of step-up and step-down transformers. Various coils can be used for GCSE physics and A-Level physics to show how transformers are used in domestic electrical appliances and in the National Grid for power transmission. Demonstrations work well with the Interscale Demonstration Meter EL52300. The core is made up of highly permeable U-shaped metal sheeting, which can be closed via two clamps with tightening screws. The cross-section of the core measures 40 x 40 mm. Contents: • Transformer core • 1x 6000 turn, 0.2 A coil, with tappings every 2000 turns • 1x 1200 turn, 1.25 A coil, with tappings at 300 & 600 turns • 1x 72 turn, 12 A coil, with tappings at 6, 30, 54, and 66 turns • 1x 600 turn, 2.5A coil, with mains input, switch and protective fuse The Premium Version is supplied in Gratnells tray with insert.

National Grid Simulation Kit

To safely demonstrate the need for high voltage transmission of electricity. This apparatus clearly demonstrates how this is achieved using the interconnected boxes through which pupils can see the components. The high and low voltage sides are clearly indicated, with resistance wires connected to either side for direct comparison of lamp brightness/energy loss. By gripping the insulated cables the energy loss can be felt in the form of heat. There are also voltmeter sockets for measuring the high voltage. Comes complete with two boxes (transmit and receive), insulated resistance wires, two mounted SBC lamps and full instructions. Touchproof, locking high voltage connectors used throughout it is virtually impossible to get an electric shock Clear lid to the casing so pupils can see how it works and trace the circuit Indicators for low/high voltage Voltmeter sockets for measuring the high voltage Supplied with 2 x kits to make up the pylons AC Power supply and Connection wires are not supplied An additional power supply is required to carry out this experiment, capable of supplying 12V at 5A. Also required are 6 x connecting leads.
