Faraday flux and induced EMF
Hold coil geometry fixed and vary the rate of field change. A large but steady field gives zero EMF; changing field creates an induced voltage.

Lenz law direction
The minus sign means the induced current creates a field opposing the change in flux. When increasing flux becomes decreasing flux, induced current reverses. Heating remains nonnegative.
Run this experiment →Self and mutual inductance
Inductance measures flux linkage per ampere. More turns increase self-inductance quadratically. Mutual inductance also depends on how well the two coils share flux.
Run this experiment →Eddy-current magnetic braking
A moving conductor develops eddy currents that resist motion. This effective-loop model shows increased braking with stronger field and smaller loop resistance.
Run this experiment →RC, LR and LC transients
Switch among capacitor charging, inductor current rise and ideal energy exchange in an LC circuit. RC and LR approach a steady state; ideal LC continues oscillating.
