   These are used to make neodymium magnets. The strength of neodymium magnets is the result of several factors. The most important is that the tetragonal Nd 2 Fe 14 B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (H A ≈ 7 T – magnetic field strength H in units of A/m versus magnetic moment in A·m 2).

3. Orders of magnitude (magnetic field) - Wikipedia

   en.wikipedia.org/wiki/Orders_of_magnitude...

   Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance (⁠ 1 / distance 3 ⁠) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]

   A seller of these [] says they do not require a soft iron keeper across the poles to prevent loss of magnetic strength over time, as alnico magnets do. Could someone please find a reliable source for this, and an explanation in thems of the properties of the materials, the hysteresis curve, or whatever.

6. Force between magnets - Wikipedia

   en.wikipedia.org/wiki/Force_between_magnets

   Magnets exert forces and torques on each other through the interaction of their magnetic fields.The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the mater
