The grade, or “N rating” of the magnet refers to the Maximum Energy Product of the material that the magnet is made from. It refers to the maximum strength that the material can be magnetized to. The grade of neodymium magnets is generally measured in units millions of Gauss Oersted (MGOe). A magnet of grade N42 has a Maximum Energy Product of […]
Neodymium magnets are a member of the rare earth magnet family. They are called “rare earth” because neodymium is a member of the “rare earth”elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.
All of the pull force values we specify have been tested in our laboratory. We test these magnets in two different configurations.Case 1 is the maximum pull force generated between a single magnet and a thick, ground, flat steel plate. Case 2 is the maximum pull force generated with a single magnet sandwiched between two thick, ground,flat steel […]
Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla). Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).
Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Many types of steel are ferromagnetic because of the iron content. Steel is an alloy of iron, carbon and other elements.
Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron […]
There are several simple methods that can be used to identify the (Scientific) North and South poles of neodymium magnets. 1) The easiest way is to use another magnet that is already marked. The North pole of the marked magnet will be attracted to the South pole of the unmarked magnet. 2) If you take […]
Ambient temperature: since sintered NdFeB magnet has negative temperature coefficients of remanence Br and coercivity Hc, the temperature will demagnetize the magnet to some extent, reversibly or irreversibly. The loss is also recoverable or irrecoverable. Environment humidity: NdFeB magnet usually has to be coated to prevent it from corrosion because the naked material is very […]
