Physics - Electromagnetism - Faraday's law - Flux and EMF Relationship
An interactive simulation with a coil in a magnetic field. Controls: B (0-1T), A (0.01-0.1 m²), N (1-200 turns), angle θ (0-90°), and a 'time to change' slider. Display: Current flux Φ = NBAcosθ and induced EMF = NΔΦ/Δt. Students investigate: (1) Increase B gradually → EMF is proportional to rate of
