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

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
