The website (HM Wire) linked by the article appears to have been copied directly from the previous revision of the article; the writing process for this article makes it rather unlikely that it was copied from the HM Wire website. That said, perhaps it is poor form to link to an external website containing a copy of the article?18.80.2.239 (talk) 02:28, 3 June 2008 (UTC)[reply]

The link seems to have snuck back in some time in the last three years. I'll remove it. Kendall-K1 (talk) 15:06, 29 September 2011 (UTC)[reply]

History

What is the history of magnet wire? Who invented it? Who made it possible for the Brush Electric dynamo in the 1870s, the arc light era, before modern synthetic resins became available--largely after 1920?

What is the history of wire coating? Wire towers? Varnishes applied in turpentine? Gutta percha? —Preceding unsigned comment added by 76.216.90.210 (talk) 18:39, 31 March 2009 (UTC)[reply]

Magnet wire in potentiometers

I do not think that magnet wire is usually used in potentiometers that, if wire wound, will be made of resistance wire and not copper or aluminium.

It seems like perhaps varnished wire might fit the bill but magnet wire which is traditionally a highly conductive wire would not.

Agreed. Even if nichrome is varnished for insulation, it's still primarily there for its resistance, not as magnet wire. Andy Dingley (talk) 18:04, 7 October 2014 (UTC)[reply]

Maybe there are some potentiometers which use magnet wire with partially removed varnish like it's typically done in variable autotransformers. However, I don't object the removal of this text, because the text didn't contain references and it was not stated that magnet wire is used this way.

If there are such potentiometers, then there will be citations to them.

I've never seen such a potentiometer. Copper magnet wire is too low resistance as a potentiometer: the low resistance means high current and that means more power and more heating. Then you get temperature coefficient problems. Andy Dingley (talk) 21:00, 7 October 2014 (UTC)[reply]

I meant that the magnet wire is used just for the tap, not as the main resistive element. Mario Castelán Castro (talk) 21:52, 7 October 2014 (UTC).[reply]

The "tap" is generally a carbon (usually bronze loaded carbon, for lower resistivity) brush, attached with a solid metal spring or a braided copper lead. The part-bared varnish of the windings are the same resistance wire as the main winding. Andy Dingley (talk) 22:30, 7 October 2014 (UTC)[reply]

You can make massive amounts of magnetic wire with cheap copper and a standard oven at 500k to sell on ebay or what not. — Preceding unsigned comment added by 69.255.27.70 (talk) 23:05, 14 March 2015 (UTC)[reply]

Hexagonal Magnet Wire

This does not appear to be commonly available anywhere. It may be a theoretical wire shape to maximize packing. Maybe someone makes a custom extrusion for hex magnet wire, but there are no easily found sources doing a basic internet search.

Please remove the reference to hexagonal magnet wire unless a reference and/or source can be provided. — Preceding unsigned comment added by 173.25.254.189 (talk) 10:47, 18 October 2015 (UTC)[reply]
