摘要：

This paper focuses on the acquisition and frontend processing of magnetic field information in pulsed magnetic field measurements. Based on the Faraday electromagnetic induction principle, a magnetic field measurement probe was designed, and a front-end processing circuit for pulse magnetic field induction electromotive force was developed for this probe. The sensing probe has a MHz bandwidth response capability, making it well-suited for covering pulse magnetic field applications. The front-end processing circuit is based on analog operational amplifiers and integrates amplification, filtering, and integration circuits. Finally, PSpice simulation software was used to simulate the design. The simulation results, along with experimental results, demonstrate that the magnetic field probe and front-end processing circuit designed in this paper have advantages such as high bandwidth and fast response.
