Halbach Array Magnets 250mm x 60mm k=4 (Assembled) | Made To Order

Halbach Array Magnets – 250mm x 60mm | k=4 (Assembled) | Made to Order

The Halbach Array Magnets – 250mm x 60mm | k=4 (Assembled) is a precision-engineered magnetic assembly designed to produce an exceptionally strong, highly directional magnetic field on one face while significantly reducing the magnetic field on the opposite side. Constructed using premium neodymium rare earth magnets arranged in a carefully calculated Halbach array configuration, this high-performance assembly delivers superior magnetic efficiency for advanced industrial, scientific, research, and engineering applications.

With overall dimensions of 250mm x 60mm, this k=4 Halbach Array is supplied fully assembled and is made to order, ensuring each unit is manufactured with precise magnet orientation and alignment for optimal magnetic performance. The k=4 configuration is designed to maximise magnetic flux density on the working face while minimising stray magnetic fields on the reverse side, making it significantly more efficient than conventional magnet assemblies.

Halbach Arrays are widely used in industries requiring powerful directional magnetic fields, including magnetic separation systems, linear motors, magnetic levitation (MagLev), robotics, automation, renewable energy, scientific research, laboratory equipment, precision sensors, particle accelerators, and advanced manufacturing. Their ability to concentrate magnetic energy where it is needed improves efficiency, reduces magnetic interference, and enables more compact equipment designs.

Whether you're developing a custom machine, designing a research project, or integrating a high-performance magnetic assembly into OEM equipment, the 250mm x 60mm k=4 Halbach Array provides exceptional magnetic performance, engineering precision, and long-term reliability.

Why Choose a Halbach Array?

A Halbach Array is an advanced magnetic arrangement in which each individual magnet is orientated in a specific sequence to concentrate the magnetic field onto one face of the assembly while greatly reducing the field on the opposite side. This innovative design allows for a stronger usable magnetic field, improved efficiency, and reduced unwanted magnetic interference compared to traditional magnet layouts.

The k=4 configuration is engineered to provide an optimised magnetic field distribution suitable for demanding industrial and scientific applications where magnetic precision and efficiency are critical. By directing more magnetic energy toward the working surface, Halbach Arrays can often achieve higher performance without increasing the physical size of the assembly.

Each array is professionally assembled to maintain accurate magnet orientation and spacing, ensuring reliable performance throughout its service life. As a made-to-order product, every assembly is manufactured with meticulous attention to quality and consistency.

Please Note

This product is manufactured to order, and production lead times may vary depending on manufacturing schedules and material availability. Please contact our team for current lead times or to discuss custom project requirements.

Halbach Arrays contain multiple powerful neodymium magnets that generate extremely strong magnetic forces. Handle with care during transport, installation, and operation to avoid pinch injuries and damage to surrounding equipment.

Keep the assembly away from pacemakers, medical implants, magnetic storage devices, and sensitive electronic equipment. The array should not be disassembled, drilled, machined, or modified, as this may permanently affect the magnetic field distribution and compromise performance.

If your application requires a different array size, k-value, mounting method, or a custom-designed Halbach Array, Frenergy Magnets Magnetics can manufacture bespoke magnetic assemblies tailored to your specific engineering and performance requirements.
