Magnetism and electromagnetism
Revision notes for Magnetism and electromagnetism in AQA Combined Science: Trilogy (8464). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- Poles of a magnetThe poles of a magnet are the places where its magnetic forces are strongest.
- Magnetic fieldsThe region around a magnet where a force acts on another magnet or on a magnetic material is called the magnetic field.
- ElectromagnetismWhen a current flows through a conducting wire, a magnetic field is produced around the wire.
- Fleming's left-hand rule (HT only)When a conductor carrying a current is placed in a magnetic field, the magnet producing the field and the conductor exert a force on each other.
- Electric motors (HT only)A coil of wire carrying a current in a magnetic field tends to rotate.
