FAQ

 

*1  

Q)Are you a Magnet factory or trading company ?
A) We are one of the leading magnet manufactures in Dongguan ,welcome to visit our factory .

 

*2  

Q)Does the magnet quality guarenteed ?

A)Yes ,we can guarentee the magnets we ship to you is of 100% good quality as you order ,if there is any product quality problem or products broken during shipping ,we will bear 100% responsibility for you ,you can ask for related refund or replacement . 

 

*3

Besides ,the fastest production time is 3working days for the urgent orders .


*4

Q)How does the magnet 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 magnet grade, same thickness, larger surfacearea with lower gauss.

*5   

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 a solid magnetic surface, such as a steel plate.
 
*6  
Q) If I stick 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 will have a combined pulling force of 90 lbs when stick together .


 *7  
Q)Do neodymium magnets lose strength over time ?
A)They do not 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 .
