Abstract

An all-band magnetic sensor is provided. The all-band magnetic sensor comprises an induction coil, a voltage measurement module, and an integrator; the induction coil is used for generating an induced electromotive force according to magnetic flux passing therethrough; an impedance transformation circuit is connected to the output end of the induction coil and used for improving the loop resistance of the induction coil; the voltage measurement module is electrically connected to the impedance transformation circuit, and used for measuring the induced electromotive force generated by the induction coil; and the integrator is electrically connected to the voltage measurement module, and used for expanding a bandwidth.
