Gadolinium Magnet Generator.

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?

It sounds like you're dealing with a gadolinium alloy.

No it is pure 99,99 % certified probe. Above 16 degrees C it is just paramagnetic and therefore still attracted a mangnet.
It is a gross misunderstanding to assume that gd is nonmagnetic above Curie temp.

[nestor89]

My sample says 99.999 pure and it absolutely will not detach from a neo under any temp (up to neo's curie).  I spent some time reading up on GD more carefully this morning and I don't think it ever becomes non-magnetic.  It is either ferromagnetic or extremely paramagnetic with the Curie point marking the end of ferromagnetism and the beginning of extreme paramegnetism.  GD is so paramagnetic above 68F that I cannot tell the difference between the two states.

So before any more can be done here, we must answer this question:

1. Is there in fact a point of non-magnetism (which would actually be extremely weak paramagnetism since everything is either ferro or para) when GD passes from ferromagnetic to paramagnetic?

2. If so, how long does GD remain non-magnetic?

ferromagnetism:  magetized probe remains magnetic even if magnetic field which magnetized probe is put away. some of elementary magnets stay ordered

paramagentism: as soon as magnetic field is put away all elementary magnets disorder themselves again

in both states probe is attracted by permanent magnet or electro magnet applying a magnetic field

in paramagnetic state gd drops not at curie temperature but more or less above curie temperature. depending on the force of the magnetic field. so if you use weak magnet gd drops near curie temp e.g. 26 degrees C. If you iuse strong neodym magnet it may not drop at 60 degrees C. The higher the temperature the more are the elementary  magnets shaken. If force of temperature + gravetity are stronger as applied magnetic field gd drops.

QuoteEkim'1. Is there in fact a point of non-magnetism (which would actually be extremely weak paramagnetism since everything is either ferro or para) when GD passes from ferromagnetic to paramagnetic?

Yes.use a weak magnet to see it

QuoteEkim'2. If so, how long does GD remain non-magnetic?

Permanent above its curie

no that is not precise. gd is non magnetic as long as no external magentic field is applied which aligns the elementary magnets of the probe

[nestor89]

I need a laser thermometer so I can see the GD changing temp in response to a magnetic field.

Spacing the neo would have the same effect as a weaker magnet.
I have not observed any state of non-magnetism in GD so far.
If there is one, it's miniscule and will be very hard to exploit.
I think GD is either ferromagnetic or paramagnetic at all times.

I'm starting to be suspicious of that video with the GD rotor.

i am suspicious too. the wheel may be turned by the water flow like in a water mill.

however i still not rule out that such motor making use of temp differences may work

acctually we are working on such motor. however the temp difference needs to be high in our set up in order to turn a wheel

you may harvest energy if there is a temp difference which can be used however that is no pepetuum mobile
