How do electricity transformers work? - Explain that Stuff· How does a transformer work? A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it.The strength of the magnetism (which has the rather technical name of magnetic flux density) is directly related to the size of the electric current.
