The invention provides a device and a method for measuring a magnetic field of an electromagnetic pulse in a system in order to solve the technical problems that the test environment of the electromagnetic pulse in the system generated by a pulse ray source is complex and severe, the test difficulty is large, and the measurement method is limited, so that available experimental data is scarce. According to the device, in a vacuum-resistant cavity, pulse rays are adopted to irradiate a metal cavity to generate electromagnetic pulses in a system, a shielding lead plate is utilized to protect a magnetic field detector, magnetic field signals of the metal cavity are transmitted to an optical receiver through optical fibers, and measurement signals are recorded through an oscilloscope. And simulating to realize magnetic field measurement of electromagnetic pulse in the system. Measurement of pulse magnetic field signals in a photoelectron and ray coexistence environment is realized, and effective acquisition of th
