Electromagnetic induction
Electromagnetic induction is the process of generation of electric current in a conductor due to a change in magnetic flux. It was discovered by Michael Faraday.
- Faradays Law: Induced emf is proportional to the rate of change of magnetic flux.
- Lenzs Law: The direction of induced current opposes the change causing it.
Key idea: Changing magnetic field induces emf/current
Applications: Generators, transformers, induction cooktops, motors
