A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits.
A transformer is a device with two or more magnetically coupled windings (or sections of a single winding). A time varying current in one coil (called the primary winding) generates a magnetic field which induces a voltage in the other coil (called the secondary winding). Degaussing coil-a coil used to demagnetize parts. 2  Voice coil-a coil used in a moving-coil loudspeaker, suspended between the poles of a magnet. 3  When the audio signal is passed through the coil, it vibrates, moving the attached speaker cone to create sound waves.
