electromagnet: A magnet made of an insulated wire coiled around an ironcore (or any magnetic material such asiron, steel, nickel, cobalt) with electric current flowing through it to produce magnetism.
While iron is typically used, other materials can be used as well. If you can get black magnetite sand (ebay) you can mix it with a minimal amount of epoxy to make a castable core in essentially any shape. Black sand, being very finely divided into microcrystalline grains, is easily magnetizable but will store absolutely no permanent magnetization due to the iron particles' magnetic domains being bound in the silicate matrix of the sand. So once magnetized, when the magnetizing source is removed, the induced field in the core will collapse quickly with no remanence. This makes black sand’s electromagnetic response similar to the engineered high frequency inductor core material Metglas, at a much lower price and in forms that would be difficult (expensive) to achieve with Metglas.
