N42 Neodymium Cylinder Magnet 10mm dia. x 20mm thick Diametrically Magnetized (2-Pole)

N42 Neodymium Cylinder Magnet 10mm dia. x 20mm thick Diametrically Magnetized (2-Pole)

We can produce the NdFeB Permanent Neodymium Magnets in different sizes, different shapes, different grades (strengths and temperature ratings), different coatings/finishings and different magnetizations as part of our custom magnet (made-to-order) service.

Motor and Generator (Core Applications): This is the primary function. In various types of permanent magnet motors, hub motors, and generators, radially magnetized magnets efficiently provide a rotating magnetic field, serving as a critical component that determines device performance.

Sensors and Instrumentation: Used in magnetic sensors, speed sensors, position sensors, etc., to detect physical quantities by utilizing their stable magnetic fields.

Magnetic couplings and bearings: In contactless transmission magnetic couplings and low-friction permanent magnet bearings, power transmission or levitation support is achieved using radial magnetic fields.

Speakers and Acoustic Devices: Used in earphones, speakers, and other equipment as the core component of the driving unit, converting electrical signals into sound.

The main industrial applications of diametrically magnetized neodymium magnets with two poles are as follows:

Why diametrical magnetization is used

A diametrically magnetized magnet has its north and south poles located on opposite sides across the diameter, rather than on opposite axial ends. This configuration is particularly suitable for rotating applications, because rotating the magnet changes the magnetic field direction around a fixed sensor.

Common industrial advantages include:

• Compact rotary position sensing
• High magnetic strength in a small package
• Precise angular detection
• Contactless operation
• Compatibility with Hall-effect and magnetic sensors
• Suitable for high-speed rotational systems
