The motor effect
The motor effect is the force experienced by a current-carrying conductor when it is placed in a magnetic field. Loudspeakers and headphones use this effect to convert an electrical signal into sound.
Step-by-step lessons covering AQA GCSE Physics 7.2.4 Loudspeakers (HT only) for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Build a strong grip on equations, units and Key Stage 3 fundamentals before tackling the more demanding topics like electromagnetism, the particle model of matter and space physics.
