Gadolinium Magnet Generator.

As I understand it the difference in attraction to a magnet by Gd doesn't really vary much from below to above its Curie point. If you want to use something that actually does change a lot, use Nickel. Its Curie point is quite a bit higher but still in range that you can attain by chemical reactions or focussed sunlight.

ok. thank you tk.

ct of nickel is 360 C.

neodym magnet looses magnetization around 80 C and ferrit magnet around 250 C

I do not know how magnetic paramagnetic nickel will be above ct. however i think with the means available to us it does only make sense to use gd for fun experiments.

@markscoffman yes I've got some great ideas to try with chemicals for example two pieces gadolinum in washing soda solution should be fairly passivated by the insoluble oxide layer and thus should yield interesting result on the meter if we pass a magnet back-n-forward over one electrode.lanthanum (in zippo lighter-flints) becomes amazingly passive in solutions of alkali and lanthanum is a direct relative of gadolinium.I'l be damned if we can pickup a voltage reading from two gadolinium electrodes with a STATIONARY magnet.but let's see what result ekim gets with the coils first before plunging into chemistry.

oxyd layer of gd does not stick to probe but will flake off. gd may therefore not be passivated by oxyd layer

The rate of flake-off may be slowed down under alkali.remember,atmospheric air has co2 and water in it,acidic,corrosive,penetrating
