Abstract
An improved capacitively coupled conducting-paper analog to simulate the two-dimensional magnetic vector potential field of multiple uniformly distributed source regions is discussed. A null method is used in obtaining the flux distribution, and a differential probe-amplifier combination is employed in finding flux density infarmation. Output of the analog is readily used to calculate reactance, short-circuit forces, and stray-load losses of power transformers.
