The motor effect
An electric motor uses the force on a current-carrying conductor in a magnetic field to produce rotation. In a simple motor, a coil of wire is placed between the north and south poles of a magnet, so the magnetic field points horizontally from north to south across the coil.
Step-by-step lessons on AQA GCSE Physics 7.2.3 Electric motors (HT only). Each one builds up to exam-style questions. 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.
