a unit of magnetic flux in the cgs system of units. The maxwell was named in honor of the British physicist J. C. Maxwell. Its abbreviation in international usage is Mx. A maxwell is the magnetic flux that passes in a homogeneous magnetic field having an induction of 1 gauss (G) through a cross section of 1 cm2 that is normal to the direction of the field: 1 MX = (1 G) × (1 cm2). The maxwell can also be defined on the basis of the phenomenon of electromagnetic induction as the magnetic flux which, on decreasing uniformly to zero in 1 sec in an enveloping closed circuit, generates an electromotive force equal to 1 abvolt (a cgs unit of potential difference equal to 10−8 volt); 1 MX =10−8 weber.
