What unit is the magnetic force of the magnet? What is the meaning?

Magnetic force or magnetization is called magnetic field intensity in physics. Magnetic material such as iron and steel is a good path of magnetic field line. The path of magnetic field line is called magnetic path. In the magnetic path, magnetic potential on unit length is called magnetic field strength (or magnetization). The magnetic field intensity is expressed by the letter H, which is related to the magnetic potential.




H=F/L




H----- magnetic field intensity, ampere / cm;




F----- magnetic potential, ampere;




L----- magnetic circuit length, centimeter.




The magnetic potential equals the product of the current I through the coil and the number of turns of the coil W.
