Homework Help: Magnetic monopoles

  1. Mar 25, 2006 #1
    this question supposes the existence of magnetic monopoles, and then redefines maxwell's eqn's as follows

    div(B) = dm
    curl(E) = -dB/dt - Jm

    where Jm is the magnetic current density, and dm is the magnetix charge density

    we are asked to find the energy acquired by a monopole with Dirac magnetic charge hbar/e travelling 1000 km along the earth's field (10^-5 T). I'm guessing this is just work = force * distance. the only problem is that a B-field gives the force on a current element which has the dimensions Am, I don't know how to apply it to a charge that has dimensions As. thank for your help.
