Would you like to use the heating method to make the magnetic force disappear?

Answer
Do not use fire to bake directly, use electric stove to heat gradually.
For example, the most commonly used NdFeB magnet grade N-35, when the temperature of the magnet reaches more than 200 degrees, the magnetic force will decline sharply, when it reaches about 320 ~ 380 degrees, the magnetic force will disappear completely.
