This product is an arc-shaped magnet for electric vehicles, which is generally installed on a ring at the end of the handlebar. When the handlebar rotates, the magnet will rotate with the direction of rotation of the handlebar.
There are currently two types of magnets. One is a single arc length. The magnetic field strength on the surface of the magnet varies in different positions. The sensing surface of the Hall element is a little away from the magnet. When the position of the magnet changes , The intensity of the magnetic field applied to the Hall element will change accordingly, and the magnitude of the voltage output by the Hall will change.
The other is to install a small magnet on both ends of a certain arc of the ring, so that the Hall element is between the two small magnets. The magnetic field strength will be different at different positions between the two small magnets. When rotating, the intensity of the magnetic field applied to the Hall element also changes. The principle is equivalent to that of an arc magnet above, but because the intensity of the magnetic field between the two small magnets is affected by factors such as installation angle and material deformation, the overall linearity is It is not as good as a single arc-shaped small magnet.

The magnets used in hard disk drives are very strong neodymium (rare earth) magnets. Typically a magnet will have a north pole on one face, and a south pole on the other face. Hard drive magnets differ in that they act like two magnets stuck together side by side. On one face there is a north pole on the left and a south pole on the right, on the other face there is a south pole on the left and a north pole on the right....
