WebApr 28, 2024 · The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy. Once the magnetic field reaches the secondary coil, it forces the electrons within it to move, creating an electric current via electromotive force (EMF). WebNov 25, 2024 · In DC, the current flow is steady and so is the magnetic field. Since the field is steady and not changing, there is no voltage induced on the secondary and the transformer just looks like a normal coil of resistive wire to the power supply. So transformers do not work with DC currents.
