SuperMagnetMan Neodymium Ring Magnet.  Used as medical magnets, motor magnets, sensor magnets, consumer electronics magnets.  These ring magnets are strong rare earth neodymium magnets also used as automotive magnets.

1" (25.40mm) dia x 0.250" (6.35mm) ID x 1" (25.40mm) long, N50 Rare Earth Neodymium Tube Magnet / Ring Magnet, Magnetized through the length. Nickel Plated.

Minimum Order Quantity (MOQ) = 1 pc

Common Applications:  Motors, sensors, consumer electronics, and medical applications

About Large Tube Magnets:  Defined with an outside diameter (OD) equal to or greater than 1.000" (25.40mm).  The outer diameter (OD), inner diameter (ID), and length will determine the reach and profile of the magnetic field and performance of the tube magnets. 

Direction of Magnetization (DOM):  Tube 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 length
  2. Across the diameter
  3. Multiple poles on the face of the magnet
  4. Radially magnetized, with a single pole or multiple poles on the OD and ID

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 200oC
