Abstract

The motion of a closed coil passing through a magnetic field is one of the typical problems in electromagnetism, involving physical processes such as induced current generated by the coil cutting magnetic induction lines, force on a current-carrying conductor in a magnetic field, and changes in the motion state of the coil. Based on the theories of electromagnetism and dynamics, the motion states of the coil at each stage are calculated. To clearly grasp and understand the variations of physical quantities during the coil's movement through the magnetic field, the GeoGebra software is used to establish a physical model and simulate the motion of a square coil passing through a uniform magnetic field. It can intuitively and accurately analyze the variation laws of motional electromotive force, induced current, Ampere force, acceleration and velocity of the coil under different magnetic field strengths and initial velocities.
