Halbach Array Magnets 110mm x 40mm k=4 (Assembled) | Made To Order

Halbach Array Magnets – 110mm x 40mm | k=4 (Assembled) | Made To Order

The Halbach Array Magnets – 110mm x 40mm | k=4 (Assembled) is a compact, high-performance magnetic assembly engineered to generate an exceptionally strong magnetic field on one face while significantly reducing the magnetic field on the opposite side. Manufactured using premium neodymium rare earth magnets arranged in a precision Halbach array configuration, this assembled unit delivers maximum magnetic efficiency in a compact footprint, making it ideal for advanced industrial, scientific, research, and OEM applications.

Measuring 110mm x 40mm, this k=4 Halbach Array is supplied fully assembled and is made to order, ensuring every magnet is accurately orientated and permanently fixed to achieve optimum magnetic performance. The k=4 configuration concentrates magnetic flux onto the working face, allowing for higher usable magnetic strength while minimising stray magnetic fields behind the assembly.

Halbach Arrays are widely used in magnetic separation equipment, robotics, linear motors, magnetic levitation (MagLev), industrial automation, renewable energy systems, precision sensors, laboratory equipment, and scientific research. Their ability to focus magnetic energy in a single direction makes them an efficient solution where maximum magnetic performance and minimal magnetic interference are required.

Whether you're designing custom machinery, developing a prototype, or integrating a directional magnetic system into specialist equipment, the 110mm x 40mm k=4 Halbach Array provides exceptional magnetic performance, precision manufacturing, and long-term reliability.

Why Choose a Halbach Array?

A Halbach Array is a sophisticated arrangement of permanent magnets where each magnet is orientated at a specific angle relative to its neighbours. This unique magnetic configuration concentrates the magnetic field onto one side of the assembly while dramatically reducing the magnetic field on the opposite side.

The k=4 configuration is designed to maximise usable magnetic flux, providing stronger directional magnetic performance than traditional magnet assemblies of similar size. This increased efficiency allows engineers to achieve higher performance while reducing stray magnetic fields that may interfere with nearby components or sensitive equipment.

Each 110mm x 40mm Halbach Array is professionally assembled to ensure precise magnet orientation and consistent performance. As a made-to-order product, every assembly undergoes careful manufacturing and quality control to deliver reliable operation in demanding industrial and scientific environments.

Please Note

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

Halbach Arrays contain multiple powerful neodymium magnets that generate extremely strong magnetic forces. Care should be taken during handling and installation to avoid pinch injuries, damage to nearby equipment, or accidental attraction to ferrous objects.

Keep this assembly away from pacemakers, medical implants, magnetic storage media, and sensitive electronic devices. Do not disassemble, drill, machine, or modify the array, as this may permanently alter the magnetic field characteristics and reduce overall performance.

If your application requires a different size, k-value, mounting configuration, or a fully customised Halbach Array, Frenergy Magnets can manufacture bespoke magnetic assemblies tailored to your engineering and operational requirements.
