Magnetism and electromagnetism

Part of Physics (Single Science)

  • Magnetism and electromagnetism

    • Magnetic fields - CCEA

      Magnetism and electromagnetism occur because of the magnetic fields around magnets and around electric currents.

    • The motor effect - CCEA - Higher tier

      Learn about how magnetic fields interact to produce the motor effect.

    • The AC generator - CCEA

      An important application of electromagnetic induction is the AC generator. This consists of a coil of wire rotating in a magnetic field and is used in power stations in the large-scale generation of electricity to supply homes and factories.

    • The transformer - CCEA

      A transformer is a device that can change the size of an alternating current or voltage.
