How Do You Wind Step-Up Transformer Coils?
Transformers change the current and voltage passing from one circuit to another. The primary circuit is driven by an electromotive force, which is then transferred through a magnetizable material, or “core,” to the secondary circuit. The primary circuit coils around the core so that its alternating current can induce magnetism in the core. The core’s alternating magnetic field then induces a current in windings of the secondary circuit. The ratio between the primary and secondary windings around the core determine whether the transformer steps up voltage or steps it down. Prepare two wires to be wrapped around the core. Use only insulated wiring, not bare; otherwise, the transformer won’t work. The ends of the wires will need to be stripped, to be attached later to the primary and secondary circuits. The secondary coil will have more windings around the core than the primary, to step up the voltage, so its wire can be longer. Though the wires need not be the same length, they should be
