0.030" (0.75mm) dia x 0.039" (1mm) long, Set of 25 pcs, N50 Rare Earth Neodymium Cylinder / Rod Magnet, Magnetized across the diameter. Nickel Plated.

Minimum Order Quantity (MOQ) = 1 set

Common Applications:  Medical devices, sensors, consumer electronics, holding applications, and automotive

About Micro Cylinder Magnets:  Defined with a diameter between 0.0039” (0.1mm) – 0.039” (1mm).  The diameter and the length will determine the reach and profile of the magnetic field and performance of the cylinder magnets. 

Direction of Magnetization (DOM): Cylinder 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 thickness
  2. Across 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 200oC
