Surfing through Ebay recently, found several merchants for neodymium magnets,
many shapes and sizes or magnets. Have considered trying my hand at making
an alternator/generator, say a smaller version of Hugh Piggot's stuff, perhaps
using the picoturbine designs.
I'm wondering if magnet shape makes a difference? The examples I see on
Piggot's site use a thin rectangular magnet laying flat, but the shapes
available are cubes, "thick" rectangles, spheres, discs, thick discs, rings,
cyclinders etc. Virtually any symmetrical shape looks available. My gut tells
me that a long thin magnet is the way to go; I'm looking at an inexpensive set
of 10 cylindrical-shaped magnets, 7/16" radius x 1.5" length. Am I correct in
assuming that these would be better than similar magnets of only 0.5" length?
TIA
