We describe a technique that allows the simulation of mixed magnetic and el
ectronic circuits. Magnetic components are described in terms of lumped par
ameter primitive parts, which are interconnected at magnetic 'nodes'. Elect
rical and magnetic variables are treated in exactly the same manner. Method
s of modelling hysteresis and eddy current effects are considered. As an ex
ample of a mixed system, an active Hall effect current transducer is analys
