Describe and recognise the dynamo effect.
Electricity can be generated by:
- moving a wire near a magnet;
- moving a magnet near a wire.
Label a diagram of a DC generator to show the coil, the magnets and the commutator.
Describe that a DC generator is a motor working in reverse.
Describe that in the UK, mains electricity is supplied at 50Hz.
Describe that a voltage is induced across a wire when the wire moves relative to a magnetic field.
Describe that a voltage is induced across a coil when the magnetic field within it changes.
Describe the effect of reversing the direction of the changing magnetic field.
Describe that an alternating current is generated when a magnet rotates inside a coil of wire.
Describe that electricity in a power station is generated when an electromagnet rotates inside coils of wire.
Describe how changing the speed of rotation of the electromagnet’s coil(s) affects the size and frequency of the voltage generated.
Describe how changing the number of turns on the electromagnet’s coil(s) affects the size of the voltage generated.
