Halbach Array Assemblies Types, planar and circular Halbach Arrays, Halbach Cylinders and Rings, Straight Halbach Array

The most commonly seen example of a Halbach array is the flexible refrigerator magnet. These thin, flexible magnets are often printed on for use as refrigerator magnets or on the backs of cars. If sticking to a steel surface is your goal, there is an even better option: the Mounting Magnet. Mounting magnets use a steel channel or cup to redirect the magnetic field from the backside of a single magnet, which roughly doubles the pull strength you might expect from the magnet alone. Halbach arrays can also be configured in other shapes. A ring magnet with multi-pole magnetization, or a ring made up of smaller arc segments can be used in this way. HSMAG Magnets also offers Arc Segment magnets. Halbach Array is most commonly used to produce a magnetic field utilizing permanent magnets arranged in a 90° orientation change between magnetic elements, which amplifies the magnetic force. Both planar and circular Halbach Arrays can produce a magnetic field similar to what a powered solenoid (Electromagnet) would create with smaller size, lower cost, and easier maintenance. Planar Halbach Arrays control the magnetic field to one side of the array, while a circular Halbach Arrays concentrate the magnetic field on the ID or OD.

What would you want? Where are they actually used?

Straight Halbach Array
Our neodymium magnets have the hole parallel to the magnetization direction. The north and south poles are on faces where there is a hole.

Check out a common refrigerator magnet
The most commonly seen example of a Halbach array is the flexible refrigerator magnet. These thin, flexible magnets are often printed on for use as refrigerator magnets or on the backs of cars. They are much weaker than a neodymium magnet (only 2-3% of the strength). HSMAG Magnets can offer refrigerator magnet for your requirements.

Sticking to a steel surface
If sticking to a steel surface is your goal, there is an even better option: the Mounting Magnet. Mounting magnets use a steel channel or cup to redirect the magnetic field from the backside of a single magnet, which roughly doubles the pull strength you might expect from the magnet alone.

Halbach Cylinders and Rings
Halbach arrays can also be configured in other shapes. A ring magnet with multi-pole magnetization, or a ring made up of smaller arc segments can be used in this way. Different magnet configurations will yield different directions and strengths of the magnetic field within the hole. We can also offer Arc Segment magnets

Applications of Halbach Arrays

Halbach Array is most commonly used to produce a magnetic field utilizing permanent magnets arranged in a 90° orientation change between magnetic elements, which amplifies the magnetic force.
Planer Halbach Arrays are typically used for holdings, fixturing, linear coupling applications, etc.
Circular Halbach Arrays (OD iteration) can be used in rotors for brushless DC motors, magnetic couples, power generations, etc.
Circular Halbach Arrays (ID iteration) are used to constrain plasma, steer, sort and accelerate moving charged particles, and impart oscillations
