The gaussis the cgs unit of measurement of a magnetic field B, which is also known as the "magnetic flux density" or the "magnetic induction". It is named after German mathematician and physicist Carl Friedrich Gauss. One gauss is defined as one maxwell per square centimeter. The cgs system has been formally superseded by the SI system, which uses the tesla (T) as the unit for B. One gauss equals 〖1*10〗^(-4) tesla(100 μT). According to the centimeter gram second system of units (cgs), the gauss is the unit of magnetic flux density B and the equivalent of esu/〖cm〗^2, while the oersted is the unit of magnetizing field H. One tesla is equal to 〖10〗^4 gauss, and one ampere per meter is equal to 〖4π*10〗^(-3) oersted.
