Magnetization Direction

Axially (default) or Diametrically

Different sizes and grades can be customized.
 

Kind Tips:
Neodymium magnets can be dangerous, as they generate extremely strong pull forces,
therefore must be handled with care to avoid personal injury and damage to the magnet.
Fingers and other body parts can get severely pinched between two attracting magnets. 
Neodymium magnets are brittle, and can shatter if allowed to slam together, launching
small pcs at great speeds. Eye protection should be worn when handling these magnets.
