Tungsten lamp filaments are double coiled wire. According to wikipedia, there are 22 inches of wire in a typical 60 watt bulb. This decorative bulb, because it is cold, has a low resistance, likely only a few ohms, but the effective length is likely to be quite substantial, perhaps 40 feet or more.<p>Thus, this lamp is effectively an inductively loaded whip. <i>As long as you keep the power down, otherwise it'll become a resistive load</i><p>Tungsten is paramagnetic, which I believe means it only weakly increases the inductance of a coil made from it.
