Figure 26. 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
26). The magnet is weakened substantially.
This configuration should be avoided!
Figure 27. Magnetic Field Lines with Spacer between Magnet and Iron Shaft
If the magnet has to be mounted inside a magnetic shaft, a possible solution is to place a non-magnetic spacer between shaft and magnet, as
shown in
Figure
27. While the magnetic field is rather distorted towards the shaft, there are still adequate field lines available towards the sensor
IC. The distortion remains reasonably low.
