What's the difference between magnet wire and resistance wire? Which is better for building an electromagnet?

  • \$\begingroup\$ Vape Supplies is a srange place to buy wire. Quite likely you will find it cheaper from a regular electronic supplier like Digi-Key. \$\endgroup\$ – tomnexus Mar 25 '15 at 5:37

Resistance wire will be made of some higher-resistance material than copper and may or may not be insulated, so will have a higher resistance than the same size and length of copper wire. Resistance wire would normally be used to make a heating element.

Magnet wire is copper, with a thin "enamel" insulation, and is intended for winding coils for an electromagnet.

  • \$\begingroup\$ Some of the reviews for the resistance wire, stated they were using it for wrapping something in a vaporizer, if the resistance wire is not insulated wouldn't that cause a short? \$\endgroup\$ – HSchmale Mar 25 '15 at 1:57
  • \$\begingroup\$ I assume that the vaproizer users would take care to prevent short circuits - otherwise they won't get the desired heating. \$\endgroup\$ – Peter Bennett Mar 25 '15 at 2:27
  • \$\begingroup\$ Also, the resistance wire withstands 1500°C, while copper melts at 1084°C. But you don't want to use copper at its limit, because it changes its physical properties. E.g. It becomes weak. \$\endgroup\$ – sweber Mar 25 '15 at 6:31
