Ferrite Ring Magnet 45X22X8mm

Ferrite rings help prohibit interference to and from devices, both RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference) interference.
To demonstrate, here are some of the popular applications for ferrite rings; current transformers, narrow band transformers, EMI filters, noise filters, pulse transformers, broadband transformers, Converter and Inverter Transformers and common mode chokes.

“In applications where magnets are attracting magnets, just ensure that a North face of one magnet is attracting a South face of another magnet”

Ferrite Ring Magnet Range:

Ferrite Magnets

“A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe2O3, rust) blended with small proportions of one or more additional metallic elements, such as strontium, barium, manganese, nickel, and zinc.[1] They are ferrimagnetic, meaning they can be magnetized or attracted to a magnet. Unlike other ferromagnetic materials, most ferrites are not electrically conductive, making them useful in applications like magnetic cores for transformers to suppress eddy currents.[2] Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity).

Hard ferrites have high coercivity, so are difficult to demagnetize. They are used to make permanent magnets for applications such as refrigerator magnets, loudspeakers, and small electric motors.” https://en.wikipedia.org/wiki/Ferrite_(magnet) corrosion resistance as well as their resistance to demagnetisation attributes.
Ferrites represent more than 75% of the entire world’s Magnet utilization (https://en.wikipedia.org/wiki/Ferrite_(magnet))
