- Magnetic field
- This is the field of force operating on the magnetic charge. It is also called the magnetic field. The units are the ampere/meter [A/m] for SI units and the oersted [Oe] for CGS units. The symbol for the magnetic field is H. 1 [A/m] = 4π·10-3 [Oe]. On the Earth, there exists a magnetic field called geomagnetism.
