The system that provides suppression external to the object magnetic disturbances during magnetoencephalography was developed. Register magnetic fields of the brain can detect features of the functioning of the CNS and to determine normal or pathological activity in human regulation systems, reflecting the functional state of human health. The designed system consists of a device for registration of external magnetic fields - fluxgate magnetometer, compensation module external magnetic field - coils Helmholtz, device register magnetic fields of the brain and compensate for a homogeneously magnetic field generated by the device of compensation of external magnetic fields.
