This guide is for engineers, hobbyists, and manufacturers seeking precise rotational control in their projects. The key benefit is the magnet's ability to provide reliable rotational movement and resistance to demagnetisation. A caveat is that their specific magnetic orientation means they are not designed for maximum weight-holding capacity. The product is a 6mm diameter by 1mm thick N42 Neodymium magnet, uniquely magnetized across its diameter for applications requiring rotational force, featuring a premium, corrosion-resistant coating.

It means the magnet is magnetized across its diameter, so the north pole is on one side of the curved edge and the south pole is on the opposite side, rather than having poles on opposite flat faces.
No, diametrically magnetised magnets are not designed for maximum weight-holding capacity. They are optimised for generating rotational movement.
The magnet has a premium coating of three layers (nickel, copper, nickel) designed to reduce corrosion and provide a smooth finish, enhancing its resistance to environmental factors.
Yes, diametrically magnetised magnets are commonly used on the end of shafts to provide drive and rotational movement in motors.
While resistant to demagnetisation, Neodymium magnets have a maximum operating temperature. For N42 grade, this is typically around 80°C (176°F), but consult specific product datasheets for precise limits.
Store them away from each other, sensitive electronic devices, and credit cards. A common method is to keep them in their original packaging or separated by non-magnetic material like cardboard.
Yes, diametrically magnetised magnets can be used for reed switch applications. Proper positioning will be key to activating the switch reliably.
Verify the alignment of the magnet within the system. Ensure the opposing magnetic field or material is correctly positioned and of adequate strength. Check that the magnet's poles are oriented as intended for rotational drive.
Ensure the magnet has not been exposed to temperatures exceeding its operational limit or a very strong opposing magnetic field. Check for any physical damage to the magnet or its coating. Clean the magnet surface if dirt or debris is present.
If the coating is chipped or scratched, the underlying magnet is exposed to potential corrosion. While the magnet may still function magnetically, its lifespan and resistance to environmental factors will be reduced. Consider replacing the magnet if corrosion is likely.
Keep the magnet at a safe distance from sensitive electronics. For reed switch applications, ensure the switch is positioned optimally to detect the magnetic field from the diametrically magnetized pole orientation.
Setup: These magnets are designed for integration into mechanical assemblies. Ensure proper alignment according to your design specifications to achieve the desired rotational effect. They can be fixed using adhesives suitable for magnets and the substrate material, or by mechanical means if the design allows.
Compatibility: Compatible with materials that do not interfere with magnetic fields, such as plastics, aluminium, stainless steel, and wood. Avoid prolonged contact with ferromagnetic materials like iron or steel, as this can lead to unintended attraction or reduced magnetic effectiveness. Ensure compatibility with any electronic components, especially sensitive sensors like reed switches, by testing the magnetic field strength at the intended operating distance.
Care: Handle with care to avoid chipping or cracking, particularly at the edges. While resistant to demagnetisation, exposure to extremely high temperatures (above the Curie temperature) can permanently damage the magnet. Keep the magnet's surface clean using a dry or slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners, which can damage the premium coating. Store magnets away from sensitive electronic devices and other magnets to prevent accidental attraction or damage.
