Homework Help: Magnetic field

  1. Aug 7, 2009 #1
    hello!
    im not very familiar with electromagnetic fields and classical physics, so i turn to you for help,
    a problem:
    assume you have a magnetic dipole in center (0,0) of a xy plane,
    i want to plot the vector of the field at an arbitary point on this plane,and to plot the filedlines, how do i do this? which formulas describe the magnetic field/fieldlines?
    thankyou verymuch

    Welcome to the PF. This web page has a reasonable introduction to magnetic field. Does it help?
