Ring magnets have several advantages over other types of magnets.
Firstly, their unique shape provides a more uniform magnetic field across their circular surface, making them ideal for applications that require a consistent magnetic field.
Secondly, their compact size and shape make them easy to handle and integrate into various systems. Ring magnets also have a higher magnetic pull force compared to other magnets of similar size, which makes them ideal for applications that require a strong magnetic field.
Additionally, they can be magnetized in various orientations, which adds to their versatility. Finally, ring magnets are widely available in different sizes, shapes, and magnetic strengths, making them suitable for a broad range of applications.
Magnetization Direction
The common direction of magnetization is shown in the picture below:
1> Disc, cylinder, and Ring shape magnets can be magnetized Axially or Diametrically. 2> Rectangle magnets can be magnetized through Thickness, Length, or Width. 3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness. The special direction of magnetization can be customized as required.
Grade&Coating
Support all magnet plating, like Ni-Cu-Ni, Zn, Epoxy, Gold, Silver, etc.
1>Neodymium magnets are made of Neodymium, Iron and Boron. If left to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated.2>There are a variety of options for coatings, but nickel is the most common and usually preferred. Our nickel-plated magnets are actually triple-plated with layers of nickel, copper, and nickel again. This triple coating makes magnets much more durable than the more common single nickel-plated magnets.
3>Other options for coating are zinc, tin, copper, epoxy, silver, and gold. Customer Feedback
