Magnetic Mystery
Electricity gets the applause. Magnetism does the turning.
From the essay
When we hear the word electricity, what do we picture? Perhaps a spark jumping from a doorknob, a flash of lightning, a glowing bulb, a battery, or an unpleasant shock. Electricity is dramatic. It flashes, crackles, glows, and occasionally bites, so naturally it attracts our attention. Magnetism is much quieter. A magnetic field does not glow or make a sound, and we cannot watch it moving through space. Yet it can pull, push, lift, twist, and turn. Inside an electric motor, electricity supplies the energy, but magnetic fields produce the turning force.
