2025 Best 10 Halbach Array Suppliers in the world - Blog

Introduction to Halbach Array

A Halbach array is a special arrangement of permanent magnets that creates a strong magnetic field on one side while significantly reducing the field on the other side. This unique property makes it highly useful in a wide range of applications, such as magnetic levitation systems, electric motors, generators, magnetic resonance imaging (MRI) machines, and particle accelerators. The concept was first proposed by Klaus Halbach in the 1970s, and since then, the development and application of Halbach arrays have continued to expand.
