Okay, got the recommended Magnet to try this out (but I am still on the fence about pulling the generator apart). I might leave it to my brother to F'up, especially if the other little magnets that ordered and place on the side work like I'd like them to!
All magnets have a saturation point, meaning they can only be magnetized so much, so I don't think you'd "over-magnetize" the magnet. From the pictures, it looks like the Alnico ends are about 1" long x 3/8" wide. You could try placing a BX066 or BX088-N52, one on either end, with opposite poles onto the horseshoe.

These sturdy blocks are very strong for their size and must be handled with care to avoid being pinched between two of them. This size is useful for a wide range of magnetic applications.
