A compound derived CGS unit, the maxwell, abbreviated when Mx, is the unit for the magnetic flux. the unit was antecedently known as a line. A unit title honors James Clerk Maxwell, who presented a unified theory of electromagnetism.

Around the magnetic field of strength of these gauss, the single maxwell is the sum flux through a surface of of these square centimetre perpendicular to the field.
