Figure 9. Magnetic Field Lines in Plastic or Copper Shaft
If the magnet is mounted in non-magnetic material, such as plastic or diamagnetic material, such as copper, the magnetic field distribution is not
disturbed. Even paramagnetic material, such as aluminium may be used. The magnet may be mounted directly in the shaft
(see Figure
9).
Note: Stainless steel may also be used, but some grades are magnetic. Therefore, steel with magnetic grades should be avoided.
Figure 10. Magnetic Field Lines in Iron Shaft
If the magnet is mounted in a ferromagnetic material, such as iron, most of the field lines are attracted by the iron and flow inside the metal shaft
(see Figure
10). The magnet is weakened substantially.
This configuration should be avoided!
