●Premium quality - demagnetization resistance, corrosion resistance and oxidation resistance
●Strength and Durability - Ferrite magnets have high resistance to demagnetization, corrosion and oxidation. Our round ceramic magnet is the strongest ceramic magnet for industry, trade and DIY
●Versatile - Strong ferrite magnets can be used directly in offices, basements, garages, and warehouses for tool storage, bag sealing, and school experiments
●Use with caution - Be careful when using ceramic magnets. Strong magnetic force makes magnets attract each other. Ferrite magnets are very fragile, and the magnetic attraction of impacting each other will destroy the magnets
●Application - These ring ferrites are similar in magnetism to neodymium rare earth magnets but less expensive. These ring magnets are industrial strength and ideal for home, office, school, craft, science projects

Description
Ring Magnet Ferrite
Most widely used magnetic material because of its low cost and high coercivity (doesnt lose magnetic power easily).
Ring magnets are similar to discs, but feature a hole in the centre. The reduced volume of the magnet results in less strength, but increases their versatility - rings slide easily onto tubes or rods. Ferrite rings are available in sizes up to 145mm diameter, and with a variety of internal diameters and thicknesses.
Toroids are used to confine and guide magnetic fields.These doughnut-shaped forms are wrapped in a coil to create a substantial increase in magnetic field strength. The design allows a coil to be wound through the hole and around the outside.
Toroid Applications:
Toroids are typically used in EMI filters, medical devices, musical instruments, amplifiers, power inductors and a wide array of transformers, including broadband, pulse and high frequency transformers.
Ferrite Toroid Benefits:
The shape of the toroid achieves the highest inductance per unit of volume, and helps to distribute the coil evenly around the circumference of the magnetic core. The continuous magnetic path yields the highest effective permeability and owest flux leakage of any shape. Toroids are available in various diameters, thicknesses, permeability and types depending upon the frequency range of interest. They provide exceptionally high inductance for the physical space occupied, without interacting with adjacent components.
