получить ценуIntroduction Magnetic fields. Magnetic fields are vector quantities characterized by both strength and direction. The strength of a magnetic field is measured in units of tesla in the SI units, and in gauss in the cgs system of units. 10,000 gauss are equal to one tesla. Measurements of the Earth''s magnetic field are often quoted in units of nanotesla (nT), also called a gamma.
