Induced Potential
Induced Potential
A potential difference can be induced across the ends of an electrical conductor in two ways:
Conductor moving in a magnetic field
Conductor moving in a magnetic field
- A potential difference is induced if a conductor moves relative to a magnetic field.
Change in magnetic field around a conductor
Change in magnetic field around a conductor
- A potential difference is induced if there is a change in the magnetic field around a conductor.
Induced Potential Difference
Induced Potential Difference
We can induce a bigger potential difference in an electrical conductor (coil of wire) during electromagnetic induction in 2 main ways.
More coils
More coils
- Increasing the number of turns of coils of wire.
Faster movement
Faster movement
- Making the magnetic field change more rapidly by moving the wire or the magnet more quickly.
