1.Q:Will magnets lose their power over time?
   A:Do lose a very small fraction of their magnetism over time. For example, SmCO magnet has been shown to be less that 1% over a period of ten years.

 

2.Q:Can a magnet that has lost its magnetism be re-magnetized?
   A:If the magnet has not been damaged by extreme heat, it can be re-magnetized back to its original strength.

 

3.Q:What are the standard industry definitions of "North" and "South" Pole?
   A:The North Pole is defined as the pole of a magnet that, when free to rotate, seeks the North Pole of the earth. Similarly, the South Pole of a magnet seeks the South Pole of the earth.

 

4.Q:Can a particular pole be identified?
   A:Yes, the North or South Pole of a magnet can be marked if specified.

 

5.Q:What does "orientation direction" mean?
   A:Magnets have a “grain” in that they can be magnetized for maximum effect only through one direction.

 

6.Q:Does stacking magnets together make them stronger?
   A:Yes, stacking two or more magnets together will act similar to a single magnet of the combined size.
