Custom Halbach Array Magnet in china - Aim Magnet
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.
Types of Bar Magnet
There are two types of bar magnet:
Cylindrical bar magnet: A cylindrical rod is also known as rod magnets that have a thickness equal to larger than the diameter enabling high magnetism property.
Rectangular bar magnet: Rectangular bar magnets find applications in manufacturing and engineering industries as they have magnetic strength and field greater than the other magnets.
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 Assembies
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.
1. Make sure keep the magnets are out of reach children and pets,it is not a TOY, and small magnets will pose a choking hazard.
2. Watch your fingers, as they are very strong magnets, which are difficult to pull apart and fly together quickly from far away,so it is very easy to pinch fingers between attracting poles.
3. Keep the magnets far way from medical devices, electronic products,and magnetic media, as our magnets have strong magnetic fields which may affect and/or disrupt the functioning of these medical devices,electronic products,and magnetic media.
4. Magnets are fragile, they can crack, chip, or shatter if allowed to slam against each other. so make sure handle with care, eye protection glasses.
