One many uses for a magnet from a junk computer hard drive

I've also got these magnets holding up my drill light.

I've melted down a few of the hard disk cases and cast them in sand molds. Hopefully will be making some flywheels later in the year.

That is really cool! Is that solid magnet, or aluminum with magnet backing?

The "R" is just a paperweight not a magnet, that's just what I made with the cases. The electronics went off to the scrap dealer and I kept the magnets for projects.

I thought the magnets were solid until I tried to saw them. It would appear to be a thin metalic foil wrapping a black clay like substance which sparks when sawn.

Hmmm ... I may have to cut one a check that out. I thought they were solid also. Interesting...

Interesting. As FixJeeps says, it's worth looking into more.
