How would I melt NdFeB but still keep it magnetically strong?

I have some cracked Nd2Fe14B magnets (nickel coated) and would like to melt them down and get a single large, but still very strong magnet. How would I do this?

Based on my understanding of the process, I don't believe that this would be possible for someone to do at home.

(links from Google search "Neodymium magnet manufacture")

My understanding of the flow is that an alloy of the three materials is created in a highly temperature controlled environment using melt-spinning, then the result is ground down to a fine powder, then the power is compressed while in the presence of an extremely high magnetic field.

How do I extract useful work from a system without decreasing the energy content of that system?

Once you can answer that question, you'll have answered yours.;)
