Posted:Hi there. Someone just told me about using magnets to make a regular belly dancing sword into a temporary fire sword. You use strong magnets to hold the wick to the sword then go about dipping/spinning off/performing. I've never heard or seen of this, and a google search did not bring anything up. Does anyone have experience with this? Thanks!

Posted:Sound like a cool idea.
But heat can demagnetise the magnet.

From the site
https://www.apexmagnets.com/news-how-tos/magnet-experiments-what-happens-when-a-magnet-is-heated/
br>
"The heated magnet will not pick up the paper clips, or it will pick up very few depending on the temperature and time it was heated. When heated above 176° Fahrenheit (80° Celsius), magnets will quickly lose their magnetic properties. The magnet will become permanently demagnetized if exposed to these temperatures for a certain length of time or heated at a significantly higher temperature (Curie temperature).

Heat demagnetization is also dependent on what types of materials make up a magnet. Some types of magnets such as Samarium-cobalt (SmCo) have higher heat resistance. There are also other types of Neodymium-iron-boron (NdFeB) magnets that are not as susceptible to heat induced flux degradation.
The Science Behind It

Magnets are made up of atoms. In normal environmental conditions, these atoms align between the poles and foster magnetism. When exposed to hotter conditions, the particles within the magnet are moving at an increasingly faster and sporadic rate. This jumbling confuses and misaligns the particles, causing the magnetism to be lost."

Posted:So you would need to protect the magnets from any heat or flame. Like heat shielding or placing under the kevlar wicking. Some experimentation required.
