Factory wholesale bulk neodymium magnets magnet rings n52 ring magnet neodymium

Neodymium( NdFeB )magnets are the type of rare earth magnet commercially available and are manufactured in a wide range of shapes, sizes and grades. We are a professional magnet manufacturer. Neodymium Ring Magnets are like discs or cylinders, but with a center hole. Most neodymium ring magnets and tube-shaped magnets are axially magnetised: North and south poles are located on the flat circular surfaces (“top and bottom”). The few diametrically magnetised neodymium ring magnets with poles “left and right” are specifically marked. This type of permanent magnet can be used in science projects or experiments, medical applications, cabinetry, water conditioning, loudspeakers and other commercial and industrial purposes. The higher permeance coefficient makes Neodymium ring magnets ideal for many applications.

Product Description

Products Details

1.Material The raw materials are Nd, Fe and B. Starting from the selection of materials, high-quality neodymium-iron-boron magnets are produced with high-quality rare-earth materials  and various mixed materials.
	2.Custom Magnet Size We usually say Ring neodymium magnet sizes are Outer Diameter size x Inner Diameter size x Thickness/height size. Such as D10xD5x2mm , it is means the outer diameter is 10mm, inner diameter is 5mm, and thickness/height 2mm.
3.Tolerance For each magnet, there has a tolerance to produce, as follow: +/- 0.05 mm for the small dimension; +/- 0.1 mm for the common specification;
	4.Surface Coation Zn and Ni-Cu-Ni coating is the most popular coating.There have many plating options like Ni-Cu-Ni, Ni, Zn, Gold, Black Epoxy and so on.
5.Magnetizing Direction The normal magnetizing method of the disc neodymium magnet: Axial and Radial. With the Axial magnetizing, the magnetic spread over both flat side; with the Radial magnetizing, the magnetic spread over the surround.

FAQ: 

Q1. What are neodymium and ceramic ring magnets?
A1. Neodymium and ceramic ring magnets are circular magnets with a hole in the center. Neodymium ring magnets are made of neodymium, iron, and boron, while ceramic ring magnets are made of ceramic materials.

Q2. What are the benefits of using neodymium and ceramic ring magnets?
A2. Neodymium ring magnets are known for their strength, durability, and versatility. They have a very strong magnetic pull, making them ideal for holding applications, and their small size and shape make them easy to use in a variety of settings. Ceramic ring magnets are less expensive and have a wider temperature range compared to neodymium magnets.

Q3. What are magnet rings used for?

A3. Neodymium ring magnets are used in applications such as loudspeakers and stereo systems, motors and sensors used in automotive and other high-tech, high-value applications, and in technology such as generators that ensure critical electronic equipment stays running in places such as hospitals during power outages.

Q4. Is a ring magnet permanent?

A4. Neodymium ring magnets are disc magnets or cylinder magnets with a plain hole through the center of the magnet. Neodymium (Neo or NdFeB) magnets are permanent magnets, and part of the rare-earth magnet family.

Q5. Is the ring magnet the strongest?
A5. Neodymium (also known as Neo、NdFeb、or NIB) ring magnets are the most powerful magnets commercially available today with magnetic properties that far exceed those of other permanent magnet materials.
