The maxwell, abbreviated as Mx, is the compound derived CGS unit of magnetic flux. The unit used to be called a line. The unit name honours James Clerk Maxwell, who presented the unified theory of electromagnetism, and was established by the International Electrotechnical Commission in 1930.
1 maxwell = 1 gauss × cm2 = 10−8 weberThe weber is the related SI unit.
In a magnetic field of strength one gauss, one maxwell is the total flux across a surface of one square centimetre perpendicular to the field.
