Physicists have uncovered a hidden third form of magnetism that challenges more than 100 years of established physics. Called altermagnetism, the discovery could transform future computing and electronics while opening an entirely new frontier in quantum research.
Hold up… There was a second form of magnatism?
There are (until recently) two phases of magnetism: ferromagnetic and antiferromagnetic. The other poster who replied said “dia and para”; their heart is in the right place, but their response is entirely incorrect.
Dia and para, repelled or attracted.
