Magnet wire

<p>Magnet wire or enameled wire is a <a href="/facts/Copper/I8PEE8oX">copper</a> or <a href="/facts/Aluminium/7wmR8jYE">aluminium</a> wire coated with a very thin layer of <a href="/facts/Electrical_insulation/SfSXkrh5">insulation</a>.  It is used in the construction  of <a href="/facts/Transformer/EYYfXWrF">transformers</a>, <a href="/facts/Inductors/YnfAXB3x">inductors</a>, <a href="/facts/Electric_motor/ArD7BGDa">motors</a>, <a href="/facts/Electric_generator/5sATsUGX">generators</a>, 
<a href="/facts/Loudspeaker/tqEjnJ2z">speakers</a>, <a href="/facts/Headphones/hLd5e4Kv">headphones</a>, <a href="/facts/Hard_disk_drive/kekLSGSE">hard disk head actuators</a>, <a href="/facts/Electromagnet/3YMYtSMX">electromagnets</a>, electric guitar pickups, and other applications that require tight coils of insulated wire.
</p><p>The wire itself is most often fully <a href="/facts/Annealing_(metallurgy)/2AfoCE4X">annealed</a>, electrolytically refined copper. Aluminium magnet wire is sometimes used for large transformers and motors. The insulation is typically made of tough <a href="/facts/Polymer/eF32E50K">polymer</a> film materials rather than <a href="/facts/Vitreous_enamel/gjfb1hA8">vitreous enamel</a>, as the name might suggest.
