Generators and the National Grid

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…
