A simulation experiment platform for measuring magnetic fields using the Hall effect wassuccessfully constructed using LabVIEW．experiments can first be conducted to measure the magnetic fieldstrength along the central axis of a Helmholtz coil and observe the relationship between the Hall voltage，theexcitation current and the operating current．The magnetic field distribution on the common axis plane can alsobe examined．experimental data can be quickly processed and presented visually，yielding excellent visualisationeffects．Secondly，the simulation experiment platform enables the flexible adjustment of parameters such as theexcitation current of the Helmholtz coil，the operating current，the number of coil turns and the Hall sensitivity，thereby effectively expanding the scope of the experiments． Thirdly，three-dimensional graphics display themagnetic field distribution on the central axis plane of the Helmholtz coil，showing the magnetic fielddistribution inside and outside the coil．This helps to deepen understanding of the experimental phenomena andprinciples．Finally，the error rate of the simulation results is below 0．06%，demonstrating high precision．Thesimulation platform can be used for physics laboratory teaching in higher education institutions，as well as forextracurricular self-directed learning.
