Frequently Asked Questions

What are neodymium magnets?

Neodymium magnets (NdFeB) are the strongest type of permanent magnets available. They are made from neodymium, iron, and boron and are known for their high magnetic strength, compact size, and efficiency in various applications.

What is a Halbach array?

A Halbach array is a special arrangement of permanent magnets that enhances the magnetic field on one side while canceling it on the other. It's used in motors, sensors, and magnetic levitation systems for improved efficiency.

Can you customize magnet shapes and coatings?

Yes, we offer custom magnetization, shapes, sizes, and coatings (Ni-Cu-Ni, epoxy, gold, etc.) based on your application requirements and environmental conditions.

Do you support prototyping?

Absolutely. Our engineering team supports rapid prototyping, FEA simulation, and testing to ensure optimal performance before mass production.
