## Claims

### Claim 1

An electric tattoo machine comprising:
a tattoo machine drive being powered by and controlled by an alternating current audio signal:
an electromagnetic coil being operatively coupled to an audio signal, the electromagnetic coil generating an oscillating electromagnetic field, the electromagnet having a fixed ferromagnetic core, the electromagnetic coil having a passageway there through;
