Demountable Transformer Coil – 500 Turns, 0.5A, 8.95Ω [0580]

The 500‑Turn Transformer Coil is a robust and reliable electrical component designed for use in school physics laboratories. Suitable for KS4 and above, this coil is ideal for practical investigations into electromagnetic induction and transformer principles when used with a demountable transformer system.

Featuring 500 turns of insulated wire, the coil is rated at 0.5 amps and has a resistance of 8.95 ohms. Its lower turn count and resistance make it particularly suitable for demonstrations involving higher current, lower voltage outputs, allowing students to clearly observe how changing the number of turns affects transformer behaviour.

Designed for durability and ease of use, the coil can be easily mounted and interchanged with other transformer coils, supporting flexible experiment setups and repeated classroom handling.
