Changing magnetic flux induces potential differences

Changing magnetic flux induces potential differences

Electromagnetic induction occurs when the magnetic flux linkage through a circuit changes, or when a conductor cuts magnetic field lines. This produces an induced potential difference across the conductor.

Step-by-step lessons on Edexcel GCSE Physics 13.1 Inducing a current, covering 13.1.1 Producing an electric current by induction, 13.1.2 Factors affecting the induced potential difference, 13.1.3 Alternators and dynamos, and 13.1.4 Microphones and loudspeakers. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
