This is the transformer from the ‘Hodson’ Induction Kit. The Induction Kit (EM1973-001) has many more parts to permit many experiments relating to transformers, inductors and motors. The full kit has a pre-wound primary coil and empty bobbins for the student to wind his/her own secondary coils with various numbers of turns. This model has 4x pre-wound coils to be used for primaries and secondaries and students are not required to wind coils. This item is used only for transformer theory, turns ratios, magnetising current and many other aspects of transformers and inductors. The laminated U and I cores are held together by strong rubber bands and the laminated I core can be replaced with a plain iron core to study losses in the iron and heating due to eddy currents.
