Electromagnetic Induction: When magnetic flux linked with a circuit changes, an EMF is induced.
Magnetic Flux: It is the number of magnetic field lines passing through an area.
Faraday's First Law: EMF is induced when flux changes.
Faraday's Second Law: Magnitude of EMF is proportional to rate of change of flux.
Lenz Law: Direction of induced current opposes cause (energy conservation).
When conductor moves in magnetic field, EMF is generated.
Direction → Fleming Right Hand Rule
Property of coil to oppose change in current.
Change in current in one coil induces EMF in another.
Time constant:
Current grows/decays exponentially.
Time: 60
