Magnetic Caculations - About Rules of Thumb and Quick Calculations 1. How are energy product and magnet strength related? Magnet strength needs to be defined. Magnet strength actually is a measure of total flux in the area of interest. If greater holding strength is desired, then more Br is needed, and since holding force is [...]
China Magnets Basic knowledge, history, classification of china magnets industry, types of magnets neodymium magnets, ferrite magnets, smco, alnico,rubber magnets, injection magnets Basic knowledge, history, classification of China magnets. types of magnets China magnets industry includes sintered neodymium magnets (sintered ndfeb magnets), bonded neodymium magnets (bonded ndfeb magnets), ferrite magnets, rubber magnets, smco magnets, alnico [...]
Hard Magnetic Materials Magnetic materials can produce magnetic fields, which generate forces attracting or repelling ferromagnetic materials and other magnets. Magnetic material can be divided into soft and hard magnets. Soft magnets are those materials easy to magnetize and demagnetize, while hard magnets are difficult to do so and retain strong magnetism after the removal [...]
GUITAR PICKUP MAGNETS - AlNiCo & Ferrite The magnetic pickup mounted on the Electric guitar's body help the sound production. A vibrating string cuts through the magnetic field in the pickup to produce a signal in the pickup's coil. What the magnets in pickup look like: Two type permanent magnets are used in pickups: AlNiCo [...]
Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]
History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]
HOW TO CALCULATE MAGNETIC FIELD OF MAGNETIC FILTER BAR? Powerful NdFeB Magnetic Filter Bar,Magnet Filters Rods is made from permanent magnets, stainless steel tubes and metal frames and is used to remove ferrous parts and tramp iron in the field of medicines, textiles, foods, grains, plastics,water,heating sulutionetc. The magnets bars can be strong Neodymium magnets, [...]
Safty Advice for Using Magnets Please observe the followings to avoid injury or magnetic properties deterioration: 1 When you use the magnets, you must keep the wroking environment clean; otherwise the magnets will absorb iron dust or other particles and affect its use. 2 The magnets should be fixed when you magnetize it. The magnetic [...]
