Fundamental mode orthogonal fluxgate(FM-OFG) is low noise magnetometer because the Barkhausen magnetic noise arising from the core is suppressed by the dc bias current in the excitation. We have established a technique to operate 36 channel FM-OFG sensor array by adding the phase control section to the driving electronics in order to make easy the phase angle adjustment of each of the channel. We have succeed to measure the MCG by using the 36 channel sensor array and a lightweight magnetic shield under the environment of urban magnetic noise. The obtained MCG clearly shows amplitude distributions at the QRS-wave and T-wave similar to those measured by the SQUID MCG measurement system.
