magnet switches for sub-ohm

[2naphish]

i recently read on ecf that lower ohms (less than .25 ohm IE:cloud chasing) could result in magnets reversing polarity and sticking together. i was telling the guys at my local BM about it and they wanted details. i can't seem to find it in SEARCH. so i thought i might throw this out to the electronics guys. i do not want to pass on a myth but with the popularity of "sport vaping" i thought i would at least be able to warn those who choose to do so. any links provided would be most helpful. after i read this i noticed a disclaimer on the card that comes with BCV mods now, NOT INTENDED FOR USE BELOW .25 OHMS. i just wanna help before there is another "blast".

"22. Do I have to worry about temperature with neodymium magnets?
Yes. Neodymium Iron Boron magnets are sensitive to heat. If a magnet heated above its maximum operating temperature (176°F (80°C) for standard N grades) the magnet will permanently lose a fraction of its magnetic strength. If they are heated above their Curie temperature (590°F (310°C) for standard N grades), they will lose all of their magnetic properties. Different grades of neodymium different maximum operating and Curie temperatures. See our Neodymium Magnet Specifications Page for more details. ..."

While temps will affect the magnetic properties of magnets. Sub ohm baling won't be an issue.
I have magnets in my Hades clone and I vape well beneath the .20ohm mark with no problems.

That should not be a problem

thanks. i went and read what was available from K&J. to be on the safe side , if i ever experience a short where the button gets hot i'll swap out those magnets. what's a dollar when safety is concerned. thanks.
