What is a Halbach Array magnet?

A Halbach array is a specific arrangement of a series of permanent magnets. The array has a spatially rotating pattern of magnetism which cancels the field on one side but boosts it on the other. The major advantages of Halbach Arrays are that they can produce strong magnetic fields on one side whilst creating a very small stray field on the opposite side.  

 

*Magnetic field diagrams of rectangular and ring array magnets

Machining Capability:

We have professional team, advanced equipment and well-trained QC staff to develop different sizes and shapes magnets as customer requirements which can be ensured with very high quality and precise tolerance.Please see below dimensions of ring neodymium magnet:

OD(mm)

ID(mm) H(mm) Tol.(mm)
3-300 1-200 1-100 ±0.05 & ±0.1mm

 

Where are they actually used?

• One-sided flux is useful in many applications – data security – transportation – motor design • Halbach Arrays are inherently weight-efficient. • Arrays provide higher fluxes than monolithic magnets of the same size. Halbach arrays are also used in advanced scientific experiments such as synchrotrons and free-electron lasers, where they are known as Halbach wigglers. And are used in many applications ranging from medical to military.

 

Production process of NdFeB array magnet ring:

Raw Material Preparation→Powder Compaction→Sintering→Machining→Coating→Magnetization→Assembly into Arrays→Quality Control→Testing and Inspection

It's important to note that the production process can vary slightly depending on the specific requirements of the application and the manufacturer's processes.

Customization Process:

 Below is a brief step-by-step guide to customizing magnets, more details will be confirmed during communication.

We provide customization services. If you want to customize more complex magnets, please send us an email,thanks.

 

FAQ

 

Q1. How long is the delivery time of NdFeb

A: This is the production process diagram of Ndfeb magnet. The processing of each link takes 1-2 days. The whole production process takes about 20-25 days.

 

Q2.I would like some samples for testing, do you have samples in stock?

A: For regular size, we may have samples, such as D5X3mm original magnet.  For customized size magnets, we don't have stock, if you want to produce, you need to charge sample fee.

 

Q3. Do you support exchange and return service?If I buy a magnet and I can't use it.

A: We do not support return or exchange service. As you know, the magnet is a custom product, which is completely customized according to your requirements. This product cannot be resold to others.

 

Q4. What will you do if there is a quality problem?

A: If you have any problem after receiving the magnet, please contact us immediately and shoot a video to us. We make records and take pictures of all the details when we ship. If it's our fault, we'll take the blame. If it happened in transit, we are not responsible for it.
