Let’s break it down like a Dummies author would:
Those big cylinders you see on telephone poles are transformers. electromagnetism for dummies pdf updated
Take a loop of wire inside a fixed magnet. Run current through the loop → the loop becomes an electromagnet. It tries to align with the fixed magnet → it spins. Every power tool, drone, and EV uses this.
