How are the strong neodymium disc magnets made?

As you know, neodymium magnets come in various shapes, square, circular, strip, ring, arc, etc. Among them, circular magnet is the most common one. So, here is a question, how is the strong disc magnet made?

I knew nothing about magnet at first, like you do now. After learning, I know that disc magnet is made from cylindrical raw material. After a series of slicing and processing, the magnet can be manufacture in diameter and thickness required by customer.

As you might notice, usually disc magnet has strong magnetic force at both ends. But how come?

Actually it is depend on the magnetization direction of the magnet. For most disc magnets, they are magnetized through axle while a few disc magnets are diametrically magnetized. Magnetized through axle, also known as thickness magnetization, results in strong magnetism at both end of the disc magnet. Besides, multi-pole magnetization is available now.

In addition, magnets come in different color, white, for instance. How is it done?
You can check the link below for reference.

The color is the outcome of electroplated treatment which can be customized based on customer’s requirement. As a coating for neodymium magnet, there are a lot of option, Cu, Cr, Au, black Zn, blue-white Zn and epoxy. Those materials are different in color and time of preservation, also they have their own advantages and drawbacks that you should balance with the needs.
