Permanent ferrite magnet industry overview 1. Comparison of rare earth permanent magnet materials Permanent ferrite magnet , also known as hard ferrite, is a new type of non-metallic magnetic material, which can generate a stable magnetic field with only one external supply of magnetizing energy, thereby continuously providing magnetic energy to the outside. Permanent magnet [...]
Soft Ferrite Industry Challenge (1) Industry competition and production capacity are concentrated on low-end and mid-end products At present, there are a large number of small and medium-sized manufacturers with small production capacity and low product quality in my country's soft ferrite industry. Small-scale manufacturers have backward production technology, low production automation, and extensive management [...]
Basic Situation of Soft Ferrite Magnet Market Soft ferrite is an important variety of soft magnetic materials. Its industrial production can be traced back to the 1940s. For more than half a century, the electromagnetic properties, process maturity, production scale and automation level of soft ferrite have been continuously improved. To meet the continuously updated [...]
Overview of soft ferrite magnetic materials According to the strength of magnetism, the magnetism of substances can be divided into diamagnetism, paramagnetism, antiferromagnetism, ferromagnetism and ferrimagnetism, among which ferromagnetic and ferrimagnetic substances are strong magnetic substances. Magnetic materials usually refer to strong magnetic substances, mainly composed of transition group elements such as iron, cobalt, nickel [...]
Soft Ferrites Applications Ferrites are polycrystalline oxides manufactured by ceramic technology and belong to a class of materials that exhibit the technically useful property of ferromagnetism. In a ferromagnetic material, magnetism occurs under the influence of an externally applied field. On removals of this field, material returns to its non-magnetic state. This behaviour is termed [...]
About LLC Converter Topology Power conversion is the process of converting electrical energy from one form to the other. The devices responsible for this conversion can work to convert alternating current (AC) into direct current (DC) & vice versa. They range from simple setups like a transformer to more complex conversion systems like resonant converters. [...]
Why are Ferrite Cores Used for Antenna Coils? Antennas have been used for many years to catch waves that are invisible to the naked eye. These electromagnetic waves travel around us, carrying information that’s grabbed by the antennas & used by the application it's attached to. Since all current-carrying wires around us develop their own [...]
Know About Ferrite Cable Cores As long as electronic items surround us, electromagnetic waves will be around us too. These waves are naked to the human eye and won’t affect your day-to-day activities. Born from the flow of electric current, these, however, can affect parts of devices like the power supply cable. The cable acts [...]
Know About Ferrite Core Transformers A transformer is a device used in the distribution and transmission of alternating current (AC). It does so by stepping up (increasing) or stepping down (decreasing) the voltage to attain the desired values. Hence, in simple terms, you can understand it as a voltage control device that works on the [...]
Know About Coated & Uncoated Toroidal Cores Toroidal cores are used as power shapes in electric circuits such as inductors and transformers. They are an ideal material to use at low frequencies where large inductances are required. The cores offer the advantage of material permeability and have a uniform cross-sectional area. They do not have [...]
