    Using the principle of electromagnetic induction, a rapidly changing magnetic field is generated through a coil through which alternating current is passed. This magnetic field can create eddy currents inside metallic objects. The eddy current will generate a magnetic field, which will reversely affect the original magnetic field, causing it to emit sound from its side.
