Magnet cup direction
Magnetic production: S pole is on the center of the magnetic cup face, N pole is on the outer edge of the magnetic cup rim.
The neodymium magnets are sunken into the steel cup/enclosure, the steel enclosure redirects the N pole direction to the S pole surface, it makes the magnetic holding power more stronger!
Different manufacturer may have different pole direcrtion desgin.

Magnet Cup Using Cautions
Magnet Cup powerful attraction forces can cause serious injury. Normaly we make the S pole to be the face of all magnet cup, so the magnet cup can’t attract each other face by face, but bigger size magnet cup, such as ME60, etc.
these magnet cups are made of neodymium magnets, and neodymium magnets are super strong than any other kinds of magnets, so the attracting power can be incredibly stronger than your imagination even they attract normal metals.
And fingers and other body parts can be pinched between two magnet cups, severe injuries can be occured if not carefull in handing.
These magnet cups can not be used in toys, espcially for bigger size magnet cups, they are not suitable for using at toys, children should not be allowed to handle neodymium magnet cups.
