EXAMSWALAAVI — Faraday & Lenz 3D Demo

Magnet moves through coil axis → flux changes → induced EMF & current (direction shown)

Coil turns N: 12 Coil radius (m): 1.00 Wire thickness (m): 0.06

Magnet position z (manual): -2.00 m Magnet length (m): 1.00 Magnet radius (m): 0.20

Magnet speed (m/s): 0.80 Flux width σ (m): 0.60 Load resistance R (Ω): 10.0

Instant

EMF (V): 0.000

I (A): 0.000

Model (teaching): Φ(z) ≈ k·N·A·exp(-z²/σ²). emf = -dΦ/dt → sign gives current direction (arrows).
