Ok well i was just wondering... My brother has been getting into these magnets called neodymium magnets and i was just wondering where might i be able to find these things... i mean i know like on the internet but im talking like can i go dig a whole some where and get these? If probably not then i had another idea. I have like 50 small neodymium magnets from the Magnetix thing. Would it be possible to melt these down after taking the nickel coat off of it? or would it lose its magnetivty because i changed the properties or w/e. Thanks.

Heating them up would add too much energy, causing the magnetic domains to go out of alignment. Also, all magnetic properties are lost when a magnet is liquefied because magnetism relies on all of the atoms lining up the same way, and in a liquid the orientation of the poles is constantly shifting. Magnetizing things has to occur when then substance is a solid. Do not try to melt these.
If you really want to get a huge, powerful magnet, I recommend this website:
http://www.unitednuclear.com/magnets.htm
The magnets that this place sells are the most powerful grade of neodymium available on the market.

If you heat them up you'll go past the Curie temp and they'll lose magnetism.

By considering your quarry I think 3p Magnets will be very much helpful for you.
