Set Of 5 Coils. 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 4mm sockets and are available individually or as set of coils: 50 100 turns; 200 300 turns; 300 350 turns; 400 500 turns; 550 600 turns.
