There was a second?

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.

Yeah, Paramagnetism.

Is that the kind that jumps out of aeroplanes?

This thread is already too smart for me

Pretty sure it's the other non-brand name for acetaminophen.

No, the aluminum one.
