N52 Super strong Channel Neodymium Magnet with two Countersunk Hole Rectangular Pot Magnet

Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world

2.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.

3.How long does it take for production and shipping duration?
For regular magnet orders: 5-7 working days
customized items, it would take 7-15 working days or so.
Besides, the fastest production time is 3working days for the urgent orders.

4.How does the magnet grade and magnet dimensions (L x W x H) 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;

5.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.

6.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.

7.Do neodymium magnets lose strength over time?
They don'tnaturally 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.

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