SuperMagnetMan Neodymium Sphere Magnet.  Used as medical magnets, consumer electronics magnets, sensor magnets, and positioning magnets.  Sphere magnets are strong rare earth neodymium magnets also used as automotive magnets.

0.984" (25mm) diameter, Nickel plated. N45 Rare Earth Neodymium Sphere Magnet / Ball Magnet

Minimum Order Quantity (MOQ) = 1 pc

Common Applications:  Sensors, consumer electronics, jewelry, and medical applications

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 Nickel Coating on Magnets:

  • Most common coating on magnets
  • Actually 3 layers, nickel-copper-nickel
  • Protection of the magnet from corrosion in ambient air
  • Not a protective coating from humidity, water, or salt water
  • Light protection of the magnet from chipping
  • A decorative finish
  • Shiny metallic gray finish
  • Thickness: 12-25 microns
  • Cost: Low
  • Max working Temp: Approximately 200o C
  • Gluing nickel coated magnets onto steel or plastic should be done with glue or epoxies specifically designed for magnets.
  • Main Industries: motors, medical devices (outside of body), sensors, automotive, holding, generators, pumps, thin film deposition.  Used in almost all industries
