摘要：

AC magnetic fields up to 3kHz can be measured directly using a modified high frequency fluxgate magnetometer. The amorphous metal ring core sensor was excited at 15kHz and in short circuited output mode has a -3dB bandwith of at least 2kHz. The total RMS noise level is 93pT (64mHz to 3kHz), and the noise power density decreases as 1/f over the entire frequency band.
