⚡ Energy & Dynamics — Flux in Motion

Induction does not just create a current, it creates a force that fights back. Watch energy dissipate, charges pile up, and motion settle into balance.
Every tab here is the same underlying law: emf = −N·dΦ/dt. What differs each time is WHICH factor in Φ = N·B·A·cosθ is doing the changing — B, A, θ, or N itself.
What is this?
Apparatus — drag the highlighted parts
Flux Φ through the circuit — is it changing?
Induced EMF — Lenz's law in action
Which way does the current actually flow?
