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.

An example of our circular Halbach Array:

Applications:
-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

What should be considered in a Halbach Array design?
-Operational Environment: temperature, rotation speed, liquids or gasses
-External demagnetizing fields: important for rotors
-Cost
-Lifetime
-Available room for the arrays
-Size: Halbach Arrays are assemblage of magnets, their attracting and repelling each other should be considered.
