Is the magnetic ring used on the water meter magnetized axially or radially?

The magnetic rings of water meters are usually used for impellers and gears of water meters. Most of the magnets are made of ferrite. A Taiwanese water meter customer I met before rizinia.com introduced to me that some of the magnets they use in every water meter are ferrite and some are neodymium iron boron.

Today’s topic: is the water meter magnetic ring magnetized axially or radially?

The ferrite magnetic rings used in water meters can be divided into the same-sex magnetic ring and the different-sex magnetic ring. Some of them use the same-sex magnetic ring under dry pressure, and some of them are different magnetic rings. There is no definite way of magnetization. According to the purpose of customers, there are radial magnetization and axial magnetization.
How many poles is the magnetization pole number of water meter magnetic ring?
According to rizinia.com, the magnetic ring of water meter is usually multi pole magnetized, and there are more two pole magnetization and four pole magnetization.
