Abstract：To ensure the efectiveness and accuracyof the verification of low-frequency magnetic field probes during intermediate checks，amethod basedon the principle thatthe Helmholtzcoil emitsauniform，fixed-frequency，and fixed-intensity magnetic feld，the paper proposesaverification method forlow-frequencymagneticfeld probes during intermediatechecks.First，throughtheoreticalcalculations，thetheoreticalcurrentsandvoltagesrequiredforaseriesof targetmagneticfeldswereobtained.Accordingtothismethod，anexperimentaldevicewasdesigned，andacalibrated sensitivemagneticfeldprobewasusedtotestthemagneticfieldgeneratedbytheHelmholtzcoil，therebyverifying the reliabilityof theexperimental device.Finaly，theexperimental devicewasutilized toverifythelow-frequencymagnetic field probe under test，proving the excellent practicality of this method.
