The World's Strongest "Environmentally Friendly Magnet"? LG Develops New Materials to be used in various digital products According to South Korea's "Dong-A Ilbo", LG Innotek, a subsidiary of LG, said that it has jointly developed an "environmentally friendly magnet" with the world's strongest magnetic force with the magnet specialized company "Sacred Forest Advanced Industries". Heavy [...]
42 Strange Things Salvaged with Powerful Magnets You are standing on the wooden pier by the lake, calm and serene. The wind ruffled your hair and you can't help but think, in this moment, you are completely healed. Just then, someone was standing by the muddy lake, dragging a huge set of rusted armor out [...]
If Magnet Keeps Doing External Work, Will Its Magnetism Become Weaker? The problem itself is actually a misunderstanding of magnets. Magnets can do work, but they do not consume their own magnetism in the process of doing work. Magnets look magical, but they are actually not mysterious. The principle is very similar to that of [...]
Why is the US Military Hypersensitive to a Chinese Magnet? Some time ago, during a routine inspection of the F-35 fighter jets, the US military "suddenly" discovered that there were actually Chinese-made magnets on the turbine engines of these fighter jets! This is incredible. The U.S. military has regulations prohibiting the procurement and use of [...]
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 [...]
Inductor, Magnetic Core, Magnetic Material Powder Servo Molding Machine Application Powder servo molding machines are widely used in powder metallurgy, magnetic materials, inductance integrated molding, precision ceramics, 5G filters, cemented carbide, fasteners, stamping molding, new energy, lithium batteries, auto parts, 3C and other industries, especially It is suitable for pressing and forming of complex products [...]
Desktop Scanning Electron Microscopy—Sampling Method for Magnetic Materials In this issue, we will talk about the method of using a desktop scanning electron microscope to observe the sample preparation method of magnetic materials. Generally, demagnetization is required before analysis. The main reasons are as follows: 1. Generally, the lens and scanning coil of a desktop [...]
