Abstract

An AC magnetic flux density standard system was constructed for calibration in KRISS magnetometers and for the testing of the magnetic field characteristics of sensors and materials in the frequency range below 20 kHz. This system consists of an AC magnetic field converter, a Helmholtz coil, a voltage comparator, a voltmeter, a standard resistor, and a computer with a program for automatic measurement. The expanded uncertainty (k=2) is 0.2% in the range of 1 Hz to 20 kHz.
