Topics in Electromagnetic Induction
Faraday's Laws and Basic Concepts
- First Law: Whenever magnetic flux through a closed circuit changes, an EMF is induced
- Second Law: Induced EMF is proportional to rate of change of magnetic flux
- Magnetic flux φ = B·A = BA cos θ, measured in Weber (Wb)
Lenz's Law and Direction of Induced Current
- Lenz's Law: Direction of induced current opposes the change causing it
- Induced current creates magnetic field opposing flux change
- If flux increases, induced current opposes increase; if flux decreases, induced current opposes decrease
Motional EMF
- EMF induced when conductor moves through magnetic field
- Two cases: (1) Straight conductor moving perpendicular to field (2) Rotating conductor
- Lorentz force on charges in moving conductor causes charge separation
Self-Inductance
- Self-inductance: Property of coil to oppose changes in its own current
- Symbol: L, Unit: Henry (H), where 1 H = 1 Wb/A = 1 V·s/A
- Depends only on geometry and material properties of coil
