One method was to aquire
the * powder * , build a mold , create a form to suit your
application and then you
can apply whatever * field shape * necessary to create a
custom magnet.
Naturally , the molding is done under high pressure and the field
generation at high current
. Something interesting that was being investigated , was
the application of a strong
D.C. field that was being contorted by a weaker A.C. field.
Neat stuff . . . . .

This bring up an idea I had a while
back. Is it theoretically possible
to have a spherical magnet that
has the north pole on the outside and
south on the inside? I wanted
to make make a toy with a ball that
hovers over a magnet that has north
up. The magnet for the base would
be dish shaped to keep the ball
floating in the center. I tried to cut
up a bunch of small magnets
a long time ago and glue them to a ping pong
ball with the norths out,
but it became a project that was
never
finished.
