Neodymium Ring Magnet - 13mm x 4.5mm x 5mm | Countersunk

Magnetic Product Description:

This rare earth ring magnet has an outside diameter of 13mm, an inside diameter of 4.5mm and a thickness of 5mm. It has a pull force of 3.5 kg. It is identified by the AMF magnet part number 23009A.


Uses for our rare earth ring magnets:

Neodymium Ring-shaped magnets, due to the hole, have less mass than their disc-shaped cousins and this results in a considerable reduction of magnetic field strength. However, distinct advantages arise from the unique Ring shape that makes them highly valued and particularly suitable in a range of manufacturing and design applications, especially where highly technical and extremely accurate measuring equipment is involved. The sensitivity and accuracy of magnets to detect electromagnetic impulses has been greatly amplified with the introduction of Neodymium magnetic material. For this reason, technologies like sound recording and playback equipment have become much smaller and perform to a much higher standard than pre-neodymium sound equipment. Microphones, speakers and digital recording appliances are enhanced by the inclusion of Neodymium ring magnets into modern sound studio equipment. Neodymium magnetic material has been at the forefront of technological advancement for many decades now. Neodymium Rings are major components in switches, gauges, sensors, backup systems and other types of measuring equipment where accuracy and reliability are crucial. As their power is permanent and unreliant on mains or battery power to operate, they are regarded in many fields as highly reliable and as the safest way to operate and monitor apparatus where conditions and situations can become catastrophic if systems fail. Military assets and commercial aircraft have many devices that rely on small, powerful and reliable Neodymium Ring magnets to perform safely.
