![]() Ferrite ring magnets are used often in electronics, and without them there would be neither generators nor electric motors. In medical technology, for example, large neodymium ring magnets are used when operating an MRI. Neodymium ring magnets and ferrite ring magnets can be used in many ways: depending on the strength, a ring magnet can be used in households as well as in industry, technology and crafts. At GAUDER, you will quickly find what you are looking for and can be sure that you will only receive first-class magnets. If, on the other hand, you want to use your desired magnets at hotter temperatures, then you should opt for ferrite ring magnets. If you are looking for strong super magnets that you can use at temperatures below 80☌, then neodymium ring magnets are the right choice. When choosing a GAUDER ring magnet, you should therefore pay particular attention to its environment and area of application. In turn, ceramic ring magnets are more temperature resistant and can be exposed to very high temperatures up to 200☌. Neodymium ring magnets are considered to be the strongest magnets in the world and, in direct comparison, have a higher magnetic strength at a smaller size than ferrite ring magnets. A distinction is made between neodymium ring magnets and ferrite ring magnets, whose characteristics are different.

Ceramic (or ferrite) ring magnets have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favorite. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles. Countersunk ring magnets are widely used in the construction industry for soft door closures in kitchen and bathroom cabinets.Ĭeramic Ring Magnets are similar to Ceramic Discs but with a hole in the middle, which makes them a versatile magnet option. ![]() We also have ring magnets that have a countersunk hole. Magnetic rings are often used in joinery and shop-fitting as they may be recessed and screwed into position. ![]() T he hole in center of the magnet ensures great versatility. Neodymium Ring Magnets are one of the most popular shapes of rare earth magnets. AMF Magnets offers two types of ring magnets: These mechanisms are designed to protect motors and associated apparatus in jam or 'crash stop' events by returning equipment to a risk free state. Ring magnets are often part of fail-safe devices, torque limiters or an overload clutch. Housed in linkages mediating between motors, shafts and gearing assemblages, ring magnets assist in the control of mechanical force. Components expressing insufficient mechanical intent or pressure remain stationary. Ring magnets in this context regulate at what mechanical threshold components subject to its magnetic field can move and how fast. Ring magnets are often used on a spindle, axle, shaft or rod. The outer diameter measurement is always greater than the thickness. Ring magnets are measured by the outer diameter (OD), inner diameter (ID) and thickness (T). Ring magnets are flat circular magnets (similar to disc magnets), but with a hole through the center.
