About Mid-Sized Sphere Magnets:  Defined with a diameter between 0.251" (6.375mm) - 0.999" (25.375mm).  The surface area will determine the reach and profile of the magnetic field and performance of the sphere magnets. 

Direction of Magnetization (DOM):  Sphere Magnets are manufactured so the DOM is set during the manufacturing process and cannot be changed.  Available options during manufacturing for DOM:

  1. Through the diameter

Magnetic Grades:  To view a table of grades and specs, see our Neodymium Magnet Grades & Specs

About Silver Coating on Magnets:

  • Mostly used as a decorative coating
  • Protection of the magnet from corrosion in ambient air, but is less then nickel
  • Soft metal, so can scratch easily
  • Silver finish
  • Thickness: 12-15 microns
  • Cost: Low - Medium
  • Max working Temp: Approximately 200o C
  • Main Industries: Jewelry, decorative, cosmetic, consumer products
