Neodymium MagnetA neodymium magnet (also known as NdFeB. NIB, or Neo magnet), is a type of so called ‘rare-earth’ permanent magnet. It is made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline struct Read More »
Coercive Force Coercive force is the value of the external magnetic field that brings to zero the magnetization or magnetic flux density of a magnetic body. The external magnetic field is oriented in the opposite direction Read More »
Remanence In the magnetic hysteresis loop showing the magnetic characteristics of a material, the remanence is the value of the flux density remaining when the external field returns from a high value of saturation Read More »
Magnetic Flux DensityMagnetic flux density is the amount of magnetic flux per unit surface area. The units are the tesla [T] for SI units and the Gauss [G] for CGS units. The symbol for the magnetic flux densi Read More »

Magnetic FieldMagnetic field is the force operating on the magnetic charge. The symbol for the magnetic field is H and the units are the ampere/meter [A/m] for SI units and the oersted [Oe] for CGS units where 1 [A/m] = 4π•10-3 [Oe]. The Earth itself posses a magnetic field referred to as geomagneti
Maximum Energy ProductMaximum energy product is an index expressing the performance of a permanent magnet. The units are the joule per meter cubed [J/m3] in the SI system and the gauss oersted [GOe] in the CGS system. The maxi
WASHINGTON, D.C. — Adding magnets to football helmets could reduce the risk of concussions, a new study finds. When two players collide, the magnets in each player’s helmet should repel the other’s. This should reduce the force of the collision.Football helmets now work by dispersing the energy as a
