Hi,
I would like to demagnetize a neodymium magnet with the flame of a candle. The magnet has a holding power of 22 lbs.
The curie temperature of those magnets is 310-400°C.
The magnet consists of Nd2Fe14B with a Nickel-Copper-Nickel coating.
The melting point of Nickel is 1455 °C.
Nickel gives the  silvery-white  look of de Neodymium magnets.

The flame of a candle burns at +/- 1100°C.
So in theory, I could easily bring the temperature of the magnet above the Curie temperature without damaging the coating...while using a candle flame.
The magnets consists of a fine magnetic powder which is highly flammable.
So it's important that the coating stays intact.

Is it safe to demagnetize it above a candle?

The flame of a candle burns at +/- 1100°C.

I have no independent, verifiable citation that this is incontrovertibly true.  I don't know what temp candle flames burn at generally, and I know of no way to be absolutely specific with any particular candle flame.

I'm taking the other facts at face-value.  So I suspect there is some risk of a disaster.  And I would suggest against it.

That's true.
I've read that coatings react differently.
They weaken before they melt...

For what reason you want to demagnetize the magnet.

I don't like too much the idea of putting boron in a flame, yuk.
Couldn't you heat the magnet in an oven? Most reach 350°C or a bit more.
Or a hot gas pistol to burn paints away?
Even a cooker reaches dark red, that's more than 410°C.

What are the safety measures in case boron burns with air? Full NBC clothing and autonomous oxygen bottles?
