Key Formulas
Magnetic Flux
Φ = B · A · cos(θ)
Faraday's Law
EMF = −N · (ΔΦ/Δt)
Live Readout
Values are in arbitrary simulation units (“rel.”). They show direction and proportional trends, not real volts or webers for a physical coil.
N (turns) 8
ΔΦ (flux change) 0.0000 rel.
Δt (time step) 0.017 s
ε (induced EMF) 0.00 V
Lenz's Law
Flux is not changing. No EMF is induced — Faraday's Law requires a rate of change.
