The compound derived CGS unit, the maxwell, abbreviated as Mx, is the unit for the magnetic flux. The unit was previously called a line. The unit name honors James Clerk Maxwell, who presented the unified theory of electromagnetism.

1 maxwell = 1 gauss * cm² = 10^–8 weber

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.
