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)

Halbach Array magnet arrangement is designed to produce a strong and directed magnetic field on one side while minimizing the magnetic field on the opposite side.
A Halbach Array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while reducing the field to near zero on the other side. This was achieved by having a spatially rotating of magnetization.

Ferrite is made of SrO or BaO and Fe₂O₃ as the main raw materials, and is sintered by ceramic technology. It is widely used in speakers, clicks, electric vehicles and other industrial fields.
Neodymium(NdFeB) magnets are the strongest type of rare earth magnet commercially available and are manufactured in a wide range of shapes, sizes and grades.
A ferrite magnet is a metal oxide with ferromagnetism. The magnetic properties of ferrite are also shown to have high permeability at high frequencies.
Injection molded ferrite magnets are made of a compound of ferrite powder and Nylon. To increase magnetic orientation, it is created in a magnetic field.
Rare earth permanent magnets have strong plasticity and can support customization of any size. High productivity
