Questions :

If GD is ferromagnetic below 68F, can it actually become a magnet with poles?

Is it still a magnet with poles after it goes over its Curie and then returns below 68F?

gd can be magnetized below curie temp as it is ferromagnetic below curie temp. above curie temp magetization disappears because elementary magnets disorder themselves at curie temp. however that does mot mean that gd is non magnetic above curie temp. above curie temp it is still attracted by magnet.

magnetization does not reappear  without cause if gd returns below curie temp. that would be magic

however if you apply again a magnetic field you may magnetize gd again below curie temp

@nestor89 - what I meant to ask is - can GD become a permanent magnet below its curie point?

' what I meant to ask is - can GD become
a permanent magnet below its curie point?'

Yes same as iron.but not by melting it ofcourse

@ekim I think its time to do electrical experiments with those coins.wrap it in a coil of wire and pulse some current through it(by touching the battery-pole with the wire briefly) and check if you witness with your eyes a BACKSPIKE SPARK.best to do this in dark

@profitis - thanks as always for your reply. Would the GD return to a perm mag after rising above its curie?
