This article shows how to use entropy distortion as engine.

I added implementation of this Entropy Engine model using "drinking bird" toy. It should work on temperature of normal condition 300K.

Interesting concept have you actually tested there is a temperature variation inside and outside of the magnetic field?

The drinking bird maybe a bad example as trichlorofluoromethane expands at room temperature and requires evaporation cooling to contract so you are back to front in your example unless your in my basement in Canada where it is abnormally cold :-) but I see where you are heading if you can actually show a change in temp inside and outside magnetic field I think we can come up with some interesting experiments. 

What is the actual temperature variation in terms of degrees you believe is achievable ?

Interesting concept, but you would need some calculations of the heat released during magnetization, and the temperature rise of the material and the surrounding working fluid. I don't think you get much at all.

The "drinking bird" toy works on temperature difference about 2K.
In case to use Gadolinium allow it would be possible in temperature above than its own Curie temperature 293K (20C). Here is link with graph of magnetocaloric effect for this material.

The link on pricing of material presents there.
The drinking bird toy neodymium permanent magnet grade N52 with 1.4T could be ordered from any scientific crafts store.
Good luck with experiments.
