Magnosphere is a professional Halbach Arrays manufacturer with technical design support

What is Halbach Arrays magnet?

A Halbach array is a special arrangement of permanent magnets that makes the magnetic field on one side of the array stronger, while canceling the field to near zero on the other side.?Halbach Arrays are able to achieve very high and uniform flux densities without necessitating any power input or cooling, which an electromagnet would require.

Halbach Cylinder - Circular Halbach Arrays

A Halbach cylinder is a circular Halbach array consisting of several trapezoidal or arc-shaped magnet segments with magnetic orientation vectors that rotate in order to focus the field. They are routinely built in quadrupole, hexapole, sextupole, octupole and other magnet configurations. Generally, the larger the number of discrete magnets with a corresponding number of magnetic vector angles, the more uniform the field across the inside diameter of the Halbach assembly.

Halbach cylinders are used in NMR devices, sophisticated high-torque motors, beam focusing, research and magnetic particle separation equipment for industrial, life science, R & D and medical applications.

Linear (Planar) Halbach Array

Linear Halbach arrays consist of discrete, rectangular permanent magnets mounted on a ferromagnetic backplate with varying magnetic orientations that serve to focus the field on one side of the array, producing a uniform and powerful semi-sinusoidal magnetic field. Linear (planar) arrays can also be used in a yoke configuration to produce a very powerful sinusoidal field in the gap.

We produce various types of linear (planar) Halbach arrays which are used in particle accelerators, free-electron lasers, extremely powerful linear motors and more for industrial, life science, R & D and medical applications.

Halbach-Type Magnetic Assemblies

In addition to linear and cylindrical Halbach Arrays, we custom design and build multi-level, Halbach type magnetic assemblies in multipole configurations with variable magnetic orientation patterns for industrial, scientific and medical applications. These complex assemblies produce extremely high magnetic field concentrations and high-uniformity.

ARC/SEGMENT MAGNET NEODYMIUM MOTOR MAGNETS

Strong Neodymium Arc magnets are used in building motors, generators or magnetic bearing. Since neodymium magnets N35,N36,N42,N45, 50 & N52 are much stronger than other magnets, using strong neodymium magnets can build much more powerful motors and generators assemblies.
