- 16.15 Understand that a voltage is induced in a conductor or a coil when it moves through a magnetic field or when a magnetic field changes through it.The wire cuts the magnetic field lines, inducing a current.
- 26.15 Describe the factors which affect the size of an induced voltage.More turns on the coil of wire means a greater voltage.
Moving the magnet in and out of the coil faster induces a greater voltage.
A stronger magnet increase the voltage. - 36.16 Describe the generation of electricity by the rotation of a magnet within a coil of wire and vice versa.The wire cuts the magnetic field lines, inducing an a.c. current.
