Demagnetizing Neodymium magnets in a candle flame?

  1. Jan 29, 2016 #1
    Is it possible to partly demagnetize neodymium magnets in the flame of a candle?
    Those magnets are made up of Neodymium, Iron and Borium.
    They have a Nickel-Copper-Nickel coating.
    The Curie temperature for Neodymium magnets is 310-400°C.
    Neodymium (magnetic powder) burns but does the coating prevent that?
    How does Nickel and Copper react to high temperatures?

    The Curious Temp to
    is ~ 80-200°C
    I suggest a... boiling party ツ
