How a Transformer Works

We have seen how transformers are made before but how do they actually work? Fileark gives us demonstration video about the magic that is happening inside the transformer. “The transformer is based on two principles: firstly, that an electric current can produce a magnetic field (electromagnetism) and secondly that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromagnetic induction). Changing
