Consider that both an electron and a magnetic monopole are kept at rest close to each other. Will this result any motion of the electron? If yes, please give a derivation of the equation of motion.

  • $\begingroup$ Classical electron and classical monopole? What's the mass of the monopole? $\endgroup$

  • $\begingroup$ Also to consider: what if the electron starts oriented with spin in the direction (or anti-direction) of the monopole? It's magnetic dipole moment would mean the two particles necessarily are going to be attracted or repelled. And a similar situation if the magnetic monopole can have an electric dipole moment... $\endgroup$ May 15 '15 at 6:54
  • $\begingroup$ I'm not sure whether they can have dipole moments despite of being at rest to each other. The hypothetical situation I have tried to present here is that both the electron and the magnetic monopole are free from any external electromagnetic field. There exist only pure monopole fields of an electric and a magnetic charge. $\endgroup$

  • $\begingroup$ @Subhra True, but (for example) the electron has intrinsic spin, and spinning charges (electron in a loop for example) generate a magnetic field - en.wikipedia.org/wiki/Electron_magnetic_moment $\endgroup$ May 15 '15 at 7:13

    $\begingroup$ I think Wolfram has solved the problem for you: demonstrations.wolfram.com/… $\endgroup$
