N52 30mm od x 20mm x 10mm thick Big Hole Neodymium Ring Magnets Nickel Plated Diametrically Magnetized magnetic radial ring radially magnetized Tube Magnets Big Hole

These rings are diametrically magnetized, which means they are magnetized perpendicular to the axis of the hole. The poles are located on opposite sides of the circular faces. They can be placed on a shaft to work with sensors or to generate electricity.

Dimensions: 30 mm od x 20 mm id x 10 mm thick(Out Diameter x Inner Diameter x Thickness)
Tolerances: ±0.1 mm
Material: Sintered NdFeB, Grade N52
Plating/Coating: Nickel-Plated (Ni-Cu-Ni)
Magnetization Direction: Diametrical
Max Operating Temp: 176ºF (80ºC)

Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet due to their brittle nature, and to avoid injury due to pinching.

Diametrically magnetised!
If you lay a diametrically magnetized ring magnet flat in front of you, the north pole is located, for instance, on the left half and the south pole on the right half. Consequently, these ring magnets stick together sideways, similar to the way you place backgammon pieces.

Neodymium magnets are perfect for use in dry indoor areas. Diametrically magnetised magnets are often utilised in sensor technology or for magnetic couplings or switches.
