These versatile high-performance Ring Magnets, with north and south poles on opposing circular faces, have many uses. They are used in many everyday appliances such as vacuum cleaners plus motors, generators, rotor shafts and more. Buy strong neodymium ring magnets Magnetic rings, from tiny to huge. NdFeB magnetic rings are powerful super magnets for use in industry, model making, medicine, hobby and workshop. Ring magnets can be used in many ways. Ring magnets can be used in many ways. Most neodymium magnet rings have north and south poles on the flat circular surfaces (axial magnetization). The few exceptions of neodymium ring magnets, which are diametrically magnetized, are specially marked.

Details

Magnetic rings are specified by specifying the outer diameter Ø D, the inner diameter Ø D and the height H. In most cases, the magnetization takes place axially or via the height. Ring magnets are a special type of neodymium magnet - with a hole in the middle.

Our neodymium discs are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings.

NdFeB rod and cylinder magnets are often used in power generation equipment, high performance motors, consumer electronics, magnetic sensors, high-end audio equipment, surgical instruments and high-intensity separators for industrial, medical, aerospace, automotive and commercial industries as well as consumer use.

Ring Magnets

Similar to disc magnets, ring magnets are a thin flat design featuring a central hollow or cavity. Specifications for these types of magnets are measured by the outer diameter, inner diameter and thickness. Ring magnets are most often deployed on a spindle, axle, shaft or rod. Ring magnets in this context regulate at what mechanical threshold components subject to its magnetic field can move and how fast. Components expressing insufficient mechanical intent or pressure remain stationary. Housed in linkages mediating between motors, shafts and gearing assemblages, ring magnets assist in the control and expression of mechanical force. Ring magnets are often part of fail-safe devices, torque limiters or an overload clutch. These mechanisms are designed to protect motors and associated apparatus in jam or 'crash stop' event by returning equipment to a risk free state.

Magnet force

The holding forces have been determined at room temperature on a polished plate made of steel (S235JR according to DIN 10 025) with a thickness of 10 mm by pulling the magnet vertically from the surface (1kg~10N). A deviation of -10 % (max.) in the stated values is possible in exceptional cases. In general, the value will be exceeded.

Classy look and high-quality material

Thanks to the elegant look of our Neodymium Ring Magnets, they can be placed where they are clearly visible.
