Abstract

WITHIN the past 2 or 3 years many scientists and engineers working on research and development projects in the magnetic amplifier field have come to realize that the dynamic hysteresis loop of a magnetic material plays an important role in determining the amplification and control characteristics of high-gain magnetic amplifiers. Figure 1 shows a block diagram of an excitation and test circuit which often has been used to display the dynamic hysteresis loop of a core material upon the screen of a cathode-ray oscilloscope tube.
