Product Description

Large N42 Ring Magnet Super Strong Custom Size Ring Magnets



Neodymium (NdFeB) Magnets Request for Quote


Neodymium iron boron magnets are the most powerful type of permanent magnets commercially available today, with magnetic properties that far exceed alnico and ceramic(ferrite) magnet materials. Sintered neodymium magnets offer extremely high energy product for their compact size, they have a high-magnetic remanence and much higher coercivity than other permanent magnets.. They are also relatively low-cost and available in a wide range of shapes, sizes and grades.


Neodymium magnets are the most widely used type of rare-earth magnet for industrial, technical and commercial applications, requiring strong permanent magnets. Components that were once large and heavy can now be miniaturized, often resulting in a substantial cost savings for completed magnetic assemblies and components.

1. Is it OK to print my logo on magnet product or package?
Yes. Please inform us formally before our production and confirm the design firstly based on our sample.


2.How does the magnet grade and magnet dimensions affects the Gauss Level of magnets?
Same magnet size, higher grade with higher gauss;
Same magnet grade, same surface area, the thicker, the higher gauss;
Same magnet grade, same thickness, larger surface area with lower gauss;


3.What does pulling force mean?
Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid
magnetic surface, such as a steel plate.


4.If I stick two neodymium magnets together, does their strength double?
No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined pulling force of 90 lbs when stick together.


5.Do neodymium magnets lose strength over time?
They don’t naturally lose any strength and will keep the strength permanently in the normal conditions, unless meet the high temperature over 80 degrees Celsius(℃), and then will lose the strength gradually.


6. What materials do magnets attract?
Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals.


7.How do you make our business long-term and good relationship?
a) We keep good quality and competitive price to ensure our customers benefit ;
b) We respect every customer as our friend and we sincerely do business and make friends with them
