Figure 3-7 Strip Magnet

When the pole count of a bar magnet is increased above 2, it is possible to create a strip magnet. Often these magnets are created using a low cost flexible rubberized magnetic material. However, it is also possible to obtain custom bar magnets with multiple pole pair using stronger materials such as neodymium type magnets. The polarization alternates along the length of the magnet in the x-direction with each pole pair aligned in the Z-direction.

To create a magnet of this type, increase the default number of poles from 2 to any positive even integer value. For this magnet type, the total number of poles considering both the top and bottom of the magnet should be used. The magnet shown in #GUID-6F790766-8052-448E-ABB2-16656B4B5ABD has 8 poles.

These magnet types are commonly used for linear position encoding. When moving with respect to a latch type sensor, these can provide incremental position resolution.
