The Josephson junction (JJ) consists of two superconductors connected by a thin insulating barrier, whose phase difference controls the flow of current and voltage, generating an overcurrent when the current exceeds a critical value, creating an action potential. JJ can also be combined with memristors, capacitors and other components to build a neuron model with magnetic field sensing function. Therefore, in this study, a JJ is used to driven a nonliner circuit with magnetic flux-controlled memristor (MFCM) coupled two capacitors, and then a magnetic field-sensitive neural circuit is obtained. Furthermore, dynamical model of a magnetic field-sensitive neuron and its energy function are derived by using the Kirchhoff's current and voltage theorem and Helmholtz’ law. In addition, the firing behaviors of a magnetic field-sensitive neuron and the coherent resonance phenomenon are investigated. Numerical simulation shows that the different firing modes of a magnetic field-sensitive neuron can be induced under different external stimulus and the coherent resonance phenomenon is also be occurred under a certain noise intensity. Therefore, this magnetic field-sensitive neuron is efficient and can exhibit firing behavior similar to that of biological neurons.
