The utility model discloses a high frequency magnetic field probe. The high frequency magnetic field probe comprises an annular probe coil arranged in a copper tube, wherein the probe coil is formed by winding a semi-steel coaxial cable, a tail end of the semi-steel coaxial cable which extends out of the copper tube is provided with a shielding layer, one end of an inner core of the semi-steel coaxial cable in the shielding layer is connected with an SMA connector, the other end of the inner core of the semi-steel coaxial cable in the shielding layer is connected with the shielding layer, and a resistor is connected between the two ends of the inner core of the semi-steel coaxial cable in the shielding layer. According to the high frequency magnetic field probe, by calibrating the linearity curve of the high frequency magnetic field probe and testing a standard pulse magnetic field, a strong transient electromagnetic pulse generated when a transformer station is subjected to a fault or a lightning stroke or is under switch operation can be measured, misoperation of secondary equipment can be effectively avoided, and normal operation of the secondary equipment is guaranteed.
