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?

Nah, it's the one with the chair

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