Any time an electric current flows through a conductor, a magnetic field will appear around the conductor. A changing current, and alternating current (AC), will produce a changing electromagnetic field around the conductor. If this field passes through another conductor, if it "sweeps" that other conductor, the magnetic field will induce a voltage in that conductor, and this is magnetic induction. Devices that apply this principle can be called magnetic induction units. A transformer is a good example.
