I have no idea about the numbering, but I know of at least

  • Ferromagnetism (like a fridge magnet)
  • Antiferromagnetism (opposite of ferromagnetism at an atomic level)
  • Diamagnetism (makes superconductors float)
  • Paramagnetism (like that spinny frog)

These all indicate how a material reacts to a magnetic field. This article discusses “altermagnetism”, which is somewhere between ferromagnetism and antiferromagnetism.
