  • Permanente magneet - Wikipedia

    Een permanente magneet, wordt meestal kortweg als magneet aangeduid. Soms wordt het ook trekstaal of plakijzer genoemd. Het is een voorwerp dat van zichzelf magnetisme vertoont. Dit in tegenstelling tot een elektromagneet, waarvan het magnetisme het gevolg is van de elektrische stroom door de spoel. Een permanente magneet bestaat uit ferromagnetischmateriaal waarin de ma

  • Permanent Magnets | Custom Magnets & Magnetic Assemblies

    Permanent magnets are made from special alloys (ferromagnetic materials) such as iron, nickel and cobalt, several alloys of rare-earth metals and minerals such as lodestone. Unlike electromagnets, permanent magnets produce a persistent magnetic field without the need for any external source of magnetism or electrical power.

  • Electropermanent magnet - Wikipedia

    An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The direction of magnetization in the latter piece can be switched by a pulse of current in a wire winding about the former. When the magnetically soft a
