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.

Where are Halbach Arrays actually Used?

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.

Halbach Arrays can also be configured in other shapes. A halbach array ring magnet with multi-pole magnetization or a ring made up of smaller arc segments can be used in this way.

Halbach arrays can be mainly divided to straight type and circular type base on geometry. Circular type can be further classified to O.D. iteration and I.D. iteration based on the arrangement of the permanent magnet. Different directions and strength will be yielded by different magnet configuration.
