Non-polarized / Paramagnetic-like Physical definition: In paramagnetic or pre-magnetized materials, the electron spins are in random directions and the net magnetic field is zero. Field and particle behavior: There is no specific pole; each atom or small magnetic dipole has a random orientation. In the absence of an external field, the orientations cancel out. Field line pattern: Short, random, non-coordinate lines; isotropic distribution in space. There is no polar axis. Analytical note: μ (magnetic susceptibility) is approximately μ₀; M = 0, but dM/dH > 0 (induction potential). See more
