In order to solve the challenges faced by magnetic resonance experimental teaching in medical imaging technology or intelligent medical imaging engineering，a basic simulation experimental platform for pulse magnetic resonance was built based on numerical simulation technology． This platform can achieve functions such as nuclear magnetic resonance signal detection，indirect measurement of magnetic field strength，measurement and adjustment of magnetic field uniformity，determination of ＲF pulse angle，etc．The platform supports arbitrary parameter setting and adjustment，dynamic signal acquisition and display，rapid spectrum generation and reading，sampling stop and information prompt．The virtual simulation experimental platform is easy to operate，flexible and controllable，and supports online operation of multiple terminals．It provides students with resources that can be learned everywhere and constantly for learning physical principles and observing physical phenomena，helping them understand abstract physical principles and enhancing the effectiveness of experimental teaching．
