      HI  HOPE THIS HELPS


      First law of magnetism? Like poles repel Unlike pokes attract


      Two equations governs Magnetism
      Gausses's Law for magnetism: Div (H) = 0 where H is a vector
      Ampere's Circuital Law: Curl(H) = J + dD/dt H, J and D are all vectors also.
      H is magnetic field intensity J is current density D is electric flux density

        Like poles repel - unlike poles attract.
