Halbach Array Permanent Magnet
 |
|
Halbach Array is a kind of magnet structure, which is an approximate ideal structure in engineering. The goal is to generate the strongest magnetic field with the least amount of magnets. In 1979, when American scholar Klaus Halbach was doing electron acceleration experiments, he discovered this special permanent magnet structure and gradually improved this structure, eventually forming the so-called "Halbach" magnet. |

Halbach magnetic ring The Halbach magnetic ring combines the radial and parallel arrangement of magnets. If the end effect is ignored and the permeability of the surrounding magnetic material is regarded as infinite, then the above-mentioned permanent magnet structure will eventually form a one-sided magnetic field (one-sided magnetic field). sided field), this is a distinctive feature of Halbach.
Different array modes can form different combined magnetic rings：
