Speaker Magnet And Its Effect on Sound Quality Types of magnets: 1. Alloy magnet Aluminum nickel-cobalt magnet, also known as speaker magnet. It was generally made of an internal magnetic horn. It has small power, and a narrow frequency range, it is hard and brittle. 2. Iron oxide magnet It is sintered from magnetic material [...]
The Strongest Permanent Magnet - Neodymium Magnets At room temperature, the neodymium magnet is the most powerful permanent magnet. But this is only at room temperature. Early Neo magnets had an annoying flaw: they were sensitive to temperature, and when the temperature rose, the magnetism dropped dramatically, and when it was above 100 degrees Celsius, [...]
Magnet Design Guide – Learn How to Make Your Magnets Designing your magnets can be an overwhelming task without the right information. It does not matter the type of magnet design you want – it is critical to consider possible shapes, materials, magnetic performance characteristics, and uses among others. Once you understand these 4 principles [...]
What are the Types of Magnets? There are many kinds of magnets, generally divided into permanent magnets and soft magnets. Permanent magnet is divided into two categories: The first category is: metal alloy magnets include NdFeB, SmCo and AlNiCo magnets. The second category is ferrite permanent magnet. What are the Types of Magnets [...]
What is Ferromagnetism If the atoms have magnetic moments in the material, they can be called magnetic materials. Iron, cobalt, nickel, and manganese have magnetic moments with their alloy atoms, which are common magnetic materials. Gold, silver, copper, aluminum, and other atoms have no magnetic moment and are non-magnetic materials. magnets But magnetism includes ferromagnetism, [...]
Anti-corrosion of NdFeB Magnet NdFeB magnet is very easy to be corroded.Therefore, most of the finished product to plating or coating.Routine used in surface treatment including: nickel (nickel-copper-nickel, zinc, aluminum, such as electrophoresis.If the work in a confined environment, can also be used phosphate way.strong magnetic hooks Neodymium-iron-boron magnet are used widely at present, the [...]

Hard Ferrite Magnet The hard ferrite is manufactured with SrO or BaO and Fe2O3 by ceramic process. Because of its cheaper price, and production process is relatively simple, compared with the prices of their products relatively cheap in terms of other magnets. The main raw materials of ferrite magnets is oxide, so, it could not [...]
Application of Magnetic Materials in Industry In fact, magnetic materials can be seen everywhere in our life, such as Fe3O4, that is, rust. It is a natural magnet can be seen everywhere in our life. In our industrial production, magnetic materials are extensively and ubiquitously applied. For instance, a generator for power generation, a transformer [...]
