What is a Halbach Array magnet?

A Halbach Array magnet is a specific configuration of permanent magnets that follows the principles of a Halbach array.The key feature of a Kings‘s Halbach Array magnet is the specific arrangement of magnets with alternating orientations. The magnets are positioned in such a way that their magnetic moments reinforce each other on one side and cancel each other out on the other side. This results in a focused and intensified magnetic field on the "active" side and a significantly weakened field on the "inactive" side.(as figure below)

Where are they actually used?

    Halbach Array magnets find applications in a variety of fields due to their unique magnetic properties. Some of the common areas where Halbach Arrays are used include:

  1. Electric Motors and Generators;
  2. Magnetic Levitation;
  3. Magnetic Resonance Imaging (MRI);
  4. Particle Accelerators;
  5. Linear Motors;
  6. Loudspeakers;
  7. Wind Turbines;
  8. Maglatch Systems;

These applications demonstrate the versatility of Halbach Arrays in providing efficient and focused magnetic fields, making them valuable in a wide range of engineering and scientific contexts.

 

Production process of NdFeB array magnet ring:

Raw Material Preparation→Powder Compaction→Sintering→Machining→Coating→Magnetization→Assembly into Arrays→Quality Control→Testing and Inspection

It's important to note that the production process can vary slightly depending on the specific requirements of the application and the manufacturer's processes.
