What is a Linear Halbach Array?
The linear Halbach array is a well-known planar magnetic structure that amplifies the magnetic field on one side of the array while nearly canceling the field on the other side. This unique configuration is achieved by carefully arranging discrete rectangular permanent magnets (neodymium or samarium cobalt) mounted on a ferromagnetic backplane, which can be thought of as an unfolded Halbach cylinder. The specific magnetic orientation of the array allows for more efficient use of the magnetic flux. It seems similar to pot magnets: the magnetic force is concentrated on one side.

What customization options are available for linear Halbach magnet arrays?
Customizing a linear Halbach magnet array ensures it meets the exact requirements of your project, whether you are optimizing for performance, durability or integration. Here are the key customization options to consider when ordering a magnet array for industrial, commercial or high-tech applications.
- Magnetic Strength and Field Distribution:
At the heart of any Halbach array is its magnetic strength and field distribution. You can customize the magnetic grade to fit your needs – whether it’s N35 for standard applications or N52 for maximum magnetic force.
In addition to strength, you can also adjust the field distribution. A tightly focused magnetic field is ideal for precision-driven linear motors, while a wider field may be better suited for applications such as magnetic levitation. - Temperature Resistance:
Extremely high temperatures are encountered in automotive, aerospace or specific industries. By selecting magnets with the appropriate high temperature resistance, demagnetization at high temperatures can be avoided. Customizing arrays with high temperature resistant neodymium magnets (H series, UH series or even AH series) will provide consistent functionality in high temperature environments. - Shape and Size Specifications:
Not all linear Halbach arrays fit into standard molds. The diversity of requirements may require a compact, low-profile array, or a larger configuration for industrial use. We offer full customization in shape and size. Customers can choose custom lengths, widths, and heights to fit your design needs. - Magnet Configuration:
The arrangement of magnets in a linear Halbach array directly affects performance. You can specify the pole orientation and magnetic configuration to ensure the field distribution is appropriate for your application.
- Surface Coating:
Surface coatings protect linear Halbach magnets from environmental damage and extend their life. We offer a variety of surface finishes such as nickel plating, nickel plating, epoxy coating, and rubber coating.
Of course, every industry has its own needs. In addition to considering these details when customizing linear Halbach magnet arrays, it is also important to consider the actual application to solve unique challenges. Our professional team is dedicated to helping companies fine-tune these options to ensure that your magnets are not only fully functional, but also durable and efficient.
What quality assurance is involved in the production of linear magnet arrays?
When manufacturing linear magnet arrays, proper quality control measures ensure that the finished product maintains consistent performance and long-term reliability. Osencmag follows a rigorous set of quality assurance measures to ensure that each magnet array meets industry standards and, more importantly, customer expectations.
It all starts with the materials. We use only high-quality NdFeB and SmCo to ensure strong magnetic properties. Before we begin assembling the array, we carefully test the purity and magnetic strength of the raw materials to ensure that their magnetic properties meet international standards.
Misalignment or poor construction can cause the magnetic performance of a linear magnet array to degrade, or even cause complete failure in your application. Therefore, we use advanced CNC machining, wire cutting, and laser-guided assembly techniques to ensure that each magnet is perfectly positioned.
In production, consistency is critical. You can’t rely on one-off testing alone. Instead, we perform batch testing at various stages of the manufacturing process to ensure that each product reaches the same level of quality. During batch testing, our production facility evaluates magnetic strength, alignment, and physical durability and keeps a record.
Once the linear motor magnets are built, they are rigorously tested to ensure they meet key performance indicators. The following key performance tests are performed:
- Magnetic Strength Testing: The magnetic field is measured to confirm that it meets your exact specifications, and Gauss meters and flux meters are used to evaluate the strength and direction of the field.
- Heat Resistance Testing: High temperatures can cause demagnetization. We simulate various temperature conditions to ensure that the magnets remain stable even over a specific operating range.
- Durability Testing: Mechanical stress, vibration, and pressure tests are performed on the magnet arrays to ensure that they can withstand real-world conditions without breaking or losing magnetism.
In addition to these in-house production tests, we also adhere to international industry standards such as ISO 9001 and RoHS. These certifications ensure that our products meet global benchmarks for safety, reliability, and performance.
This series of quality assurance measures is not only about preventing defects, but also about building long-term trust with our customers. We work with all our partners and production plants to perform strict quality controls to ensure that every product meets the highest standards, so you can submit your linear Halbach magnet needs with confidence.
What cost factors are involved in customizing linear Halbach arrays?
When you consider custom linear Halbach array magnetic assemblies, it helps to budget effectively and make informed decisions by considering multiple cost factors.
- Material Selection: Material is always the biggest factor affecting cost. High-strength neodymium magnets are always more expensive than ferrite materials. Using high-grade neodymium magnets costs more to produce than low-grade neodymium magnets. Applying special coatings to improve the corrosion or high-temperature resistance of linear Halbach arrays. These can all increase the total cost.
- Design Complexity: Custom linear Halbach arrays often require specialized engineering. The more complex the design, the more time and resources the engineering team needs to invest. The complexity of the linear Halbach magnets not only increases labor costs, but can also affect production time, resulting in higher overall expenses.
- Scope of Customization: The degree of customization of the product, such as specific size, shape, or magnetic force, will affect the cost. Each unique requirement may require a tailored solution. If the customer’s design requires very precise machining or specialized assembly, the manufacturing technology involved will cost extra.
- Expedited delivery cycle: Usually customers place orders in advance based on inventory, but it is inevitable that there will be negligence or serious inventory alarms. If you need to get linear Halbach magnets as soon as possible, we will also coordinate various raw materials and production departments to provide expedited production, but expedited orders are usually more expensive.
- Order volume: Generally speaking, bulk orders can reduce unit costs through economies of scale. If you want to order a large number of linear Halbach array magnets, we will calculate the most cost-effective quotation for you based on the actual situation.
- Logistics and transportation: Depending on the size, weight and order size of the linear Halbach array magnet components, shipping costs can vary greatly. International shipping involves tariffs and taxes, which will also affect your final budget.
Customizing linear Halbach arrays involves multiple factors. You should fully consider everything from materials, design to manufacturing requirements and logistics. By combining these factors, we can more effectively manage customization costs. Osencmag focuses on helping customers manage these costs while providing high-quality custom solutions tailored to your needs.
