Generators and the National Grid

HideShow resource information

The kinetic energy from power station turbines goes into a generator and comes out as electricity

Moving a magnet in a coil of wore makes electricity flow

  • You can make electricity by moving a magnet in or near a coil of wire
  • As you move the magnet, the magnetic field through the coil changes
  • This change in the magnetic field creates a voltage
  • If it's part of a complete circuit, a current will flow in the wire

Generators use magnets to make mains electricity

  • In a power station generator, a turbine turns a magnet near a coil of wire
  • This creates a voltage and a current
  • Turning the magnet faster makes a bigger voltage and current
  • To
