Electromagnetic Induction
by Anonymous · ⭐ 1 · 🍴 0
When a magnet moves toward or away from a coil, that motion alone creates a current. Change the magnet's speed to hit 2V and then 3V of induced EMF, raise the number of turns from 10 to 40 to measure how much the EMF grows for the very same motion, then flip the pole and the direction to watch Lenz's law at work — the induced current always opposes the change.
