The invention discloses an electromagnet state detection circuit, and a detection method, and belongs to the field of the electrical technology. The detection circuit comprises a microprocessor U1, aP-channel MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor), Q1, Q2, a MOSFET driving circuit and a current sampling circuit, wherein the microprocessor U1 is provided with two paths of I/O signals Brake_Ctrl1 and Brake_Ctrl2 and is also provided with an ADC (Analog to Digital Converter) sampling port Brake-Current; the drain electrode of the Q1 is connected with the anode of a diode D1,and the cathode of the diode D1 is connected with the input end of an electromagnet B1; the output end of the electromagnet B1 is connected with a resistor R7 in the current sampling circuit to be subjected to GND (Ground); the Brake_Ctrl2 is connected to the grid electrode of Q2; when the Brake_Ctrl1 is at a high level, the Q1 is conducted; and when the Brake_Ctrl2 is at a high level, Q2 is conducted. When current is introduced into the electromagnet, if the iron core of the electromagnet is mechanically clamped or the suction of the electromagnet is insufficient, a traditional method can notdetect the state of the electromagnet so as to probably bring hidden dangers to the system. By use of the detection circuit, the state of the electromagnet after electromagnet carries out execution can be detected at any moment, and therefore, the control mechanism can adopt a measure according to a detected state.
