The magnetic field repels and does not magnetize bismuth. However, bismuth develops a liquid state under specific high pressure and temperature conditions and acquires ferromagnetic properties. A ferromagnetic element generates a strong magnetization in the direction of the magnetizing field. They travel from a weaker to a stronger area of the ...
