WARNINGS:
* This is a seriously powerful magnet and is totally unsuitable for children.
All neodymium magnets are brittle; do not allow these magnets to jump together or to an iron/steel surface – they will break, crack, chip or shatter.
Serious risk of soft tissue injury if skin is trapped between magnet and steel or two magnets.

Magnets can be custom made. We supply OEM service. Rare-earth, Neodymium-Iron-Boron (NdFeB) Permanent Magnets For more information, please CONTACT US.

These are ideal for a large range of science applications, DIY and MRO uses. If you need to use an adhesive, we recommend using something that will bind to metal and whatever surface you want to glue the magnet to.

The pull is calculated using a mathematical formula and is, therefore, the theoretical maximum hold between one magnet and a mild steel plate. It does not take account of manufacturing tolerances, plating, plating thickness or variances in a mild steel plate. The vertical hold is based upon the calculated pull and is, therefore, only for guidance. Factors such as paint thickness, plasticised surfaces, movement and vibration are not taken into account.

WARNING: Neodymium magnets are unsuitable for children under 8. All neodymium magnets are brittle. Do not allow these magnets to jump together or to an iron/steel surface – they will break, crack, chip or shatter. Serious risk of soft tissue injury if skin is trapped between magnets or magnet and steel. THIS IS NOT A TOY. DO NOT INGEST

Permanent Neodymium-Iron-Boron Cylinder Magnet

As the strongest permanent magnet in the world, sintered NdFeB has excellent permanent magnetic properties and high cost performance compared with traditional permanent magnet materials. Sintered NdFeB magnets greatly expand the applications of permanent magnets. They are widely used in the fields of transportation, energy, communications, home appliances, machinery and medical equipment. Disk Rod Magnet

Neodymium magnets offer the highest (BH)max and high Hci(BH)max, the maximum energy product, of neodymium magnets is highest of any kind of permanent magnets today in the world. (BH)max at different grades of neodymium magnets is 27 to 52 MGOe. Disc Rod Magnet, Elevator Motor Magnets Sintered Neodymium N50UH

N45 Strong Neodymium Disk Rod Magnet

Neodymium magnets have extremely resistance to demagnetization with Hci, Intrisic coercive force, over 12,000 Oe. Because of very high (BH)max and Hci, neodymium magnets could be used as a reversible medium for large amount of energy transformation in miniaturized application where a strong magnetic demagnetization field exists , such as computer hard drive.

NdFeB magnet is widely applied to Machinery, Video and Audio equipment, Communication Devices, Medical Devices, Office Automation Equipment, Space Flight and Aviation, etc. More than 95% of our products are used in energy-efficient PM-motors, especially in Servo Motor, New Energy Vehicles Drive Motor, Compressor Motor, Elevator Motor, High Speed Motor, Explosion-proof Motor, etc.
