Demountable Transformer Coil – 200 Turns, 1A, 2.5Ω [0579]

The 200‑Turn Transformer Coil is a robust electrical component designed for use in school physics laboratories with demountable transformer systems. Suitable for KS4 and above, this coil allows students to carry out practical investigations into electromagnetic induction, transformers, and alternating current.

This coil is wound with 200 turns of insulated wire and is rated at 1 amp, with a low resistance of 2.5 ohms. These characteristics make it particularly suitable for experiments involving higher current and lower voltage, helping students clearly observe how turn count affects transformer output.

Designed for durability and ease of use, the coil can be quickly mounted and interchanged with other coils in a demountable transformer setup, making it ideal for both teacher demonstrations and student practical work.
