FAQ
Q: How about your delivery?
A: As soon as we receive the payment receipt, we will contact the factory to produce for you We'll help you deliver the goods as soon as possible
Q:How material grade and magnet dimensions(L x W x H) affects the Gauss Level of magnets?
A:Same magnet size, Higher grade with higher gauss Same magnet grade, same surface area, the thicker, the higher gauss Same thickness, same thickness, larger surfacearea with lower gauss
A:Same magnet size, Higher grade with higher gauss Same magnet grade, same surface area, the thicker, the higher gauss Same thickness, same thickness, larger surfacearea with lower gauss
Q: Could you give me some samples for free?
A: These are certainly ok but you need to pay the freight yourself
A: These are certainly ok but you need to pay the freight yourself
Q:What are neodymium magnets?
A:Neodymium magnets are a member of the rare earth family and are currently the strongest permanent magnets in the&n bsp;world!They are composed of neodymium, iron and boron (NdFeB)

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

Q: Do I have to worry about temperature with neodynium magnets?
A: Yes. They are sensitive to heat so do not heat them above 175°F (80°C) If you do, they will begin to lose their
magneticstrength. This normally applies only to industrial usage of ;heating the magnets, normal application will not affect
thestrength of the magnets.

Q: If I stack two neodymium magnets together, does their strength double?
A: No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs willhave acombinedpulling force of 90 lbs when stacked together.

Q: Do neodymium magnets lose strength over time?
A:No. They do not naturally lose any appreciable strength and will last your lifetime!
