suitable for KS4+. Laminated low loss core for attaching different coils to demonstrate the step up and step down transformer principle. Attractive demountable transformer with clearly labelled coils for GCSE physics and science and A-Level physics demonstrations. The principles used show how transformers are used in domestic electrical appliances and in the National Grid for power transmission. This magnetic circuit is made up of highly permeable U-shaped metal sheeting, which can be closed via two
clamps with tightening screws. 1 coil of 1000 turns, 230V with mains connector 1 coil of 500 turns, 0.5A.
