Do the sun and planets have a magnetic charge. - David Perdomo (age 10) Fl, Miami
Probably not. In order to have magnetic charge there must a source, called a magnetic monopole. The physicist Paul Dirac hypothesized that the existence of them would greatly simplify some of the properties of electromagnetism and also explain why electric charge comes in discrete amounts of multiples of that of the electron. Alas, many experiments that have searched for them have come up empty handed. See: http://en.wikipedia.org/wiki/Magnetic_monopole for more details than you want.
