Question

How does a transformer change the voltage of electricity while it is moving through the wires without actually touching the wires together?

Accepted Answer

A transformer changes voltage using two coils of wire wrapped around a shared metal core, but these coils never actually touch each other. Electricity flowing into the first coil creates a magnetic field. Because the electricity is constantly flipping back and forth, this magnetic field grows and shrinks in a steady rhythm. This pulsing magnetic force travels through the metal core and hits the second coil of wire. The moving magnetic field forces the electrons in the second coil to start flowing, creating a new current. Think of it like holding a magnet near a metal paperclip; you can pull the clip without ever touching it. By changing the number of loops of wire in each coil, the transformer can either boost or drop the voltage. If the second coil has more loops than the first, the voltage goes up. If it has fewer loops, the voltage goes down.
