d) Electromagnetic Induction

Does a voltage get induced in a conductor/coil?

Yes, when it moves through a magnetic field or when magnetic field changes through it.

Factors that affect size of voltage?

Strength of magnet

Number of turns in coil

Speed of movement

Describe the generation of electricity by the rotation of a coil within a magnetic field?

1. Coil is rotated within magentic field.

2. As it turns coil cuts magnetic field lines.

3. This induces voltage/current in coil.

4. This can be connected to an existing circuit.

Describe the generation of electricity by the rotation of a magnet within a coil of wire.

1. Magnet is rotated within coil.

2. As it turns coil cuts constantly changing magnetic field lines from magnet.

3. This induces voltage/current in coil.

4. This can be connected to an existing circuit.
