gauss(gowss) Symbol: G. The c.g.s. (electromagnetic) unit of magnetic flux density. One gauss is equal to 10–4 tesla.
a unit of magnetic induction in the cgs system of units (Gaussian and cgs emu). It was named in honor of K. Gauss. The abbreviation is G. A gauss is equal to the induction of a homogeneous magnetic field in which a linear conductor 1 cm long placed perpendicular to the induction vector of the field experiences a force of 1 dyne when a current equal to 1 unit of current in the cgs emu system flows through it. The gauss can also be defined as the magnetic induction for which a magnetic flux of 1 maxwell passes through a cross-sectional area of 1 sq cm normal to the lines of the induction. The relationship between the units of magnetic induction in the cgs system and the International System of Units (SI) is: 1 tesla (T) = 104 G. The kilogauss, which is equal to 1,000 G, is still used in practice. Until 1930 the gauss was also called the unit of magnetic field strength, equal to 79.577 amperes per meter. In 1930 the oersted was adopted by the International Technical Commission as the basic unit of magnetic field strength.
