Key Topics to Revise
1
Magnetic Flux and Faraday's Experiments
- Magnetic flux (Φ) is defined as the product of magnetic field and area perpendicular to it
- Faraday's experiments showed that relative motion between magnet and coil produces current
- Current is induced only when there is change in magnetic flux, not when flux is constant
2
Faraday's Laws of Electromagnetic Induction
- First Law: EMF is induced whenever magnetic flux through circuit changes
- Second Law: Induced EMF is proportional to rate of change of flux
- Negative sign in Faraday's law represents Lenz's law
3
Motional EMF and Applications
- EMF induced in moving conductor cutting magnetic field lines
- EMF depends on velocity, magnetic field, and length of conductor
- Direction given by Fleming's right-hand rule
4
Self-Inductance and Mutual Inductance
- Self-inductance opposes change in current through same coil
- Mutual inductance relates current in one coil to flux in another
- Inductance depends on geometry and core material
