no answer
Magnets can lose their properties when exposed to high temperatures, physical impacts, or strong demagnetizing magnetic fields. Additionally, corrosion and aging of the material can also contribute to the loss of magnetism in a magnet.
When an enzyme is heated it is denatured, which means that it can no longer function.
Ozone when heated gets decomposed. It decomposes into oxygen.
nothing
It cooks.
it will evaporate
You now have 2 bar magnets, each with half the magnetic force of the original.
