What’s the coolest and most unique thing about a transformer? It’s that there are no moving or friction parts inside it—no mechanical movement at all—and yet it can steadily transmit huge amounts of electrical energy, even over long distances. It’s pretty amazing! Its core structure is actually really simple, made up of just three things: the first set of coils, which we call the primary winding; the iron core in the middle; and the second set of coils, known as the secondary winding.
Let’s break down how it works step by step—it’s just three simple stages:

Step 1: Electricity turns into magnetism When electric current flows into the first set of coils (the primary winding), this current creates a magnetic field around itself. The electricity we use in daily life is alternating current (AC), whose magnitude and direction are constantly changing. So this magnetic field also “follows suit”—it keeps changing in strength and reversing direction, non-stop.

Step 2: Magnetic field transmission The iron core in the middle acts like a special “channel” for guiding magnetic fields. It can stably transfer the constantly changing magnetic field generated by the primary winding to the second set of coils (the secondary winding). But there’s a small requirement: to avoid wasting electrical energy and reduce losses, this iron core must have extremely good magnetic conductivity to transmit the magnetic field efficiently.

Step 3: Magnetism turns back into electricity When the second set of coils detects this constantly changing magnetic field, something amazing happens—it generates electricity on its own.

You might be wondering, how does the voltage get higher or lower? Well, the secret is really simple—it all depends on the number of turns in the two sets of coils and their ratio. For example, if the primary winding has 100 turns and the secondary winding only has 10 turns, the output voltage will drop to one-tenth of the original. This way of adjusting voltage by the ratio of coil turns is simple, reliable, and has extremely high energy conversion efficiency—that’s one of the transformer’s biggest advantages.
