Problems solved by technology

The disadvantage of this indirect display method is that usually only the effect of the magnetic field in a certain space section can be displayed, and the precise electromagnetic field distribution parameters cannot be obtained directly
This type of professional measuring instrument is aimed at specific scientific research. Although it can obtain extremely high-precision measurement results, it is not suitable for classroom teaching in terms of intuitiveness of display, interactivity of classroom experiments, and convenience of testing. The expensive price of test equipment greatly limits its application in basic teaching
[0008] In short, there is a lack of a system and method for teaching and experimenting with three-dimensional electromagnetic field theory with good interaction and the ability to visualize and reproduce electromagnetic fields
