How Currents Create Invisible Motion

You can generate a spinning magnetic field using only static, stationary coils. By shifting the timing of electrical currents sent through these loops, the resulting magnetism orbits the center like an invisible dancer.

It seems impossible that stationary wires could create rotational movement, but the trick lies in timing. By staggering the electrical phase in each coil, the peak magnetic force shifts from one point to the next in a seamless loop. This effect is the hidden heart of almost every modern electric motor in your home. Without this clever manipulation of invisible forces, our industrial world would effectively grind to a halt.
