The main material of anti-jamming magnetic ring is manganese-zinc and nickel-zinc ferrite, also called ferrite ring, ferrite core, soft magnet, which itself is not magnetic, can not pick up metal objects, the following are some differences between manganese-zinc ferrite and nickel-zinc ferrite introduced.
Constituent materials are different;
MnZn ferrites are made from oxides of iron, manganese and zinc by an electronic ceramic process. In contrast, NiZn ferrites are made from oxides of iron, nickel and zinc similarly by an electronic ceramic process.

Differences in magnetic permeability;
Mn-Zn ferrite typically has a high permeability, which makes it suitable for low-frequency interference suppression and for applications requiring a high inductance. Nickel-zinc ferrite has a relatively low permeability, but it has better high-frequency characteristics and is suitable for interference suppression in the higher frequency range.
Difference in resistivity;
Nickel-zinc ferrite has a high resistivity and can be used in frequency ranges from 2 MHz to hundreds of megahertz. The exception is common mode inductors, for which the impedance of Mn-Zn materials makes them the best choice for applications below 70 MHz; for applications from 70 MHz to hundreds of gigahertz, NiZn materials are recommended.
The 2 are different in appearance;
Nickel-zinc ferrite is usually gray-black or dark gray in color and has a relatively uniform color. The shade of color may vary slightly depending on the ratio of zinc to nickel, but is usually not too conspicuous.
Manganese-zinc ferrites are darker in color, usually dark gray to black. This shade of color is primarily related to the addition of manganese, the presence of which usually gives the ferrite a darker hue.
Difference in use;
Manganese-zinc ferrite cores are mainly used in transformers, local area networks, etc.; nickel-zinc ferrite cores are mainly used in computers, radar, and television.
In summary, the choice of which type of ferrite core to use depends on the specific application requirements, including the desired operating frequency, desired permeability, resistivity, and other factors.
