About this Object
This is a small horseshoe magnet, painted red. This magnet is good as a
"refrigerator" magnet -- for holding up papers and such on a metal surface.
A texture
is included which is supposed to look like the bubbly paint that was
used on the magnet this is based on.
The real magnet has a small circular dent on one side, with the letter G
on it (I have used the POVray logo here). The other side has a curved
dent, with "ENGLAND" written in it. (Some magnets have only the letter
G, and some magnets have nothing on either side).
On the real magnet, all of the letters are hard to read, becuase they
were cheaply cast, or because the paint is gloppy and obscures the letter.
Specs
The magnet is oriented to stick to a wall in the X-Y plane at Z=0, protruding
out in the -Z direction, and is centered around the Z axis. This is shown
in the magnet in the middle of the picture above.
The magnet has a height of 0.9925 units. The
rounded part is cylindrical, has a diameter of 1.125 units, and a center
0.43 units in the -Z direction. The magnet is 0.314 units thick.
Problems and Future Work
None of the edges are rounded, so it doesn't look as good as it should
when enlarged. There is no built-in provision for showing paint wear
and chipping along the edges. In addition to the bubbly paint, there is
also some cracking on the real magnet.
