In a dipole, why do we sometimes want to generate Oersteds in the gap and sometimes generate flux in the gap? Whats the difference, if any?
We generally measure magnetic field intensity in Gauss, but if that field is used to magnetize something else, it becomes a magnetizing force in Oersteds. Since permeability (U) equals B/H, anywhere that U=1, B will be equal to H. In the cgs system, the permeability of air is 1, the unit of magnetizing force (H) is the Oersted, and the unit of flux density is the Gauss, so Oersteds are numerically equivalent to Gauss (B=H). Note that “flux in the gap” must be divided by the area of the gap, in centimeters, to get a value in Gauss, or Oersteds.
