Magnetic Force of Inner And Outer Diameter Surface of Radially Magnetized Ferrite Ring Magnet

Is there any magnetic force on the inner diameter surface of the radially outer magnetized ring magnet? Are you also curious? Today, the Chinese magnet supplier HSMAG will introduce this problem to you.

Recently, a customer just happened to ask this question, so today I went to the sample display cabinet and took a few multi-pole magnetic rings for actual measurement.

8-pole ferrite magnet magnetized by outer diameter,The magnetic field strength of the radial plane is 1800 Gauss

The figure below shows the measurement of the magnetic field strength of the inner diameter of the ferrite, about 130 Gauss.

Through actual tests, it can be seen that the inner circle of the radially outer multi-pole annular magnet also has magnetic force, but it is much smaller. At present, there is also a radial ring, which can achieve inner and outer monopole magnetization.
