In the past few years, magnetoelectronics has emerged as a promising new platform technology in various biosensors for detection, identification, localisation and manipulation of a wide spectrum of biological, physical and chemical agents. The methods are based on the exposure of the magnetic field of a magnetically labelled biomolecule interacting with a complementary biomolecule bound to a magnetic field sensor. This Review presents various schemes of magnetic biosensor techniques from both simulation and modelling as well as analytical and numerical analysis points of view, and the performance variations under magnetic fields at steady and nonstationary states. This is followed by magnetic sensors modelling and simulations using advanced Multiphysics modelling software (e.g. Finite Element Method (FEM) etc.) and home-made developed tools. Furthermore, outlook and future directions of modelling and simulations of magnetic biosensors in different technologies and materials are critically discussed.

在过去的几年中，磁电子学已成为各种生物传感器中用于检测，识别，定位和操纵各种生物，物理和化学试剂的有前途的新平台技术。该方法基于与结合到磁场传感器的互补生物分子相互作用的磁性标记生物分子的磁场暴露。这篇综述从仿真和建模以及分析和数值分析的角度介绍了磁性生物传感器技术的各种方案，以及在稳态和非稳态下磁场下的性能变化。接下来是使用先进的Multiphysics建模软件（例如，有限元方法（FEM）等）和自制的开发工具对磁传感器进行建模和仿真。
