Part of the Edexcel GCSE Combined Science curriculum.
Edexcel GCSE Combined Science 13 Electromagnetic Induction is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the Edexcel specification (Pearson Edexcel GCSE (9–1) Combined Science (1SC0) – Topic 13 Electromagnetic induction). It covers inducing a potential difference, size and direction of an induced p.d., generators and alternating current, how transformers work, transformer calculations and the National Grid, then brings it all together with mixed retrieval and exam practice.
There are 20 short steps of about 15 minutes (roughly 5 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Electromagnetic induction, Induced potential difference, Number of turns, Magnetic field strength, Generator, Period, Transformer, Primary coil, Transformer power equation, Electrical power, National Grid and Transmission.
