# Do wires with DC current vibrate like wires with AC current (very tiny vibrations)?

Do wires with DC current vibrate like wires with AC current (very tiny vibrations)?

• They really don't have a reason to vibrate, right? Vibration occurs when something is pushing and pulling the wire over and over again. In case of DC currents, nothing is ever changing. There is no push-pull force at all. There is either only a push or only a pull and the wires come close together or go farther away once and forever they need to stay like that. – Sidarth Sep 29 at 9:30
