Topic Content:
- Laws of Electromagnetic Induction
- Faraday’s Law
- Lenz’s Law
- How to Determine the Direction of Current
The laws of electromagnetic induction are Faraday’s law and Lenz’s law .
Faraday’s Law:
This states that whenever there is a change in magnetic flux linking a circuit, an e.m.f is induced, the strength of which is directly proportional to the rate of change of the flux linking the circuit
Magnetic flux linking a coil depends on:
- The magnetic field strength
- Number of turns of the coil
- The area of each turn
Faraday’s law gives the magnitude of the induced e.m.f.
Lenz’s Law:
