3 On-Axis and Off-Axis Test

As seen in Figure 3-1, by placing magnets in different positions, there are many ways to measure angles, such as in-plane, out-of-plane, on-axis test, and many others. Different placement methods have different requirements for the magnet. Users can choose the appropriate method according to various factors such as actual application scenarios, mechanical design, and installation position.
