- I don't know who's serious and who's joking here, but for the record,
- Adams's construction is not a monopole (I believe it's a quadrupole).
- Field lines outside the sphere emerge from each pole and re-enter at the
- equator; "glue" doesn't stop them! You can't make something that violates
- Gauss's Law of Magnetism (del.B=0) by superposing things that obey it.
