Ferromagnetism & curie temperature

This mind-blowing experiment shows what happens when iron hits its Curie point (770°C). At room temperature, iron is ferromagnetic, meaning it’s strongly attracted to magnets. But as that torch cranks up the heat, the atoms start vibrating so violently that they lose their alignment!Once it crosses that magic threshold, the iron becomes paramagnetic and the magnetic pull vanishes instantly. Watch as it cools back down and suddenly "reawakens." Science is literally fire!
