How to express Ring magnet size?

We usually say Ring neodymium magnet sizes are Outer Diameter size x Inner Diameter size x Thickness/height size.
Such as D10xD5x2mm , it is means the outer diameter is 10mm, inner diameter is 5mm, and thickness/height 2mm.

What is size tolerance of ring magnet?

Neodymium magnet size tolerance: +/-0.05 or +/-0.1mm, according to different size request.

Magnetizing direction of Ring magnet

Generally the NdFeB/Neodymium ring magnets are axially and diametrically magnetised. The axially neodymium ring magnet is means one circular flat face is a North pole, the other circular flat face is a South pole with the distance between the flat faces (the disc thickness) being the distance between the poles (the magnet is magnetised along the central axis of the Neodymium ring magnet). Almost all our NdFeB/Neodymium ring magnets are supplied as axially magnetised NdFeB magnets. The diametrically neodymium rare earth ring magnet is magnetized across the diameter perpendicular to the central axis.

What is Ring magnet used for?

A.Life consumption: clothing, bag, leather case, cup, glove, jewelry, pillow, fish tank, photo frame, watch;
B. Electronic product: keyboard, electronic cigarette, display, smart bracelet, computer, mobile phone, sensor, GPS locator, Bluetooth, camera, audio, LED, Toy;
C. Home-based: Lock, table, chair, cupboard, bed, curtain, window, knife, lighting, hook, ceiling;
D. Mechanical equipment & automation: motor, unmanned aerial vehicles, elevators, security monitoring, dishwashers, magnetic cranes, magnetic filter.

Safety Warning:

1. Make sure keep the magnets are out of reach children and pets,it is not a TOY, and small magnets will pose a choking hazard.
2. Watch your fingers, as they are very strong magnets, which are difficult to pull apart and fly together quickly from far away,so it is very easy to pinch fingers between attracting poles.
3. Keep the magnets far way from medical devices, electronic products,and magnetic media, as our magnets have strong magnetic fields which may affect and/or disrupt the functioning of these medical devices,electronic products,and magnetic media.
4. Magnets are fragile, they can crack, chip, or shatter if allowed to slam against each other. so make sure handle with care, eye protection glasses.
