ADR for Middle School Science fair project (Magnetic Refrigeration)

Hi,

I'm curious about doing a middle school science fair project showing how magnetism can be used to cool Gadolinium and thus demonstrate the basis of magnetic refrigeration (ADR). From what I've read it looks like the requirements for generating the required magnetic field would make such a project impractical for a middle-school science fair project.

Is there a way to still demonstrate the ADR process, using a very small amount of magnetism (<< 1 Tesla)?

Thanks
