摘要：

A precision generating and measurement system of AC magnetic flux density was developed by using a linear low-frequency AC magnetic field converter, a quartz Helmholtz coil, a voltage comparator, a multimeter, a standard resistor, and a computer with a program for automatic measurement. The expanded uncertainty (k=2) of the calibration system is less than 0.2 % over the frequency range of 1 Hz to 20 kHz.
