The maxwell (symbol: Mx) is the CGS (centimetre–gram–second) unit of magnetic flux (Φ). [1]
The unit name honours James Clerk Maxwell, [2] who presented a unified theory of electromagnetism. The maxwell was recommended as a CGS unit at the International Electrical Congress held in 1900 at Paris. [3] This practical unit was previously called a line, [4] reflecting Faraday's conception of the magnetic field as curved lines of magnetic force, [5] which he designated as line of magnetic induction. [4] Kiloline (103 line) and megaline (106 line) were sometimes used because 1 line was very small relative to the phenomena that it was used to measure. [5]
The maxwell was affirmed again unanimously as the unit name for magnetic flux at the Plenary Meeting of the International Electrotechnical Commission (IEC) in July 1930 at Oslo. [6] In 1933, the Electric and Magnetic Magnitudes and Units committee of the IEC recommended to adopt the metre–kilogram–second ( MKS) system ( Giorgi system), and the name weber was proposed for the practical unit of magnetic flux (Φ), subject to approval of various national committees, which was achieved in 1935. [7] The weber was thus adopted as a practical unit of magnetic flux by the IEC.
The maxwell is a non- SI unit. [8]
That is, one maxwell is the total flux across a surface of one square centimetre perpendicular to a magnetic field of strength one gauss.
The weber is the related SI unit of magnetic flux, which was defined in 1946. [9]
