First of all, the research of primary school science projects cannot be studied in depth. I suggest that the topic be introduced into university electromagnetics step by step in a way similar to popular science introduction, so as to discover the beauty of science. Then, according to some simple theorems or concepts in college physics, we can do some experiments that we think can be done in the daily life of primary school students, and then verify them.

In fact, I don't think this process will involve a lot of profound knowledge at all. If you really want to explain thoroughly, you really need high skill.

So I don't think it will cause loopholes in theory.

Then I will briefly talk about how to write this research topic:

1. Introduce Maxwell's equations and the symmetry and simplicity of the four equations, which is an unspeakable beauty. It reveals the relationship between electricity and magnetism and constructs the framework of classical electromagnetism. Then we can start with these four equations and interpret the predecessor and origin of each equation.

For example, the first equation is about Gauss theorem, which shows that the electric field is an active field and can be discontinuous.

The second equation is about the loop theorem of eddy current, which was put forward by Maxwell and explained the phenomenon of magnetic power generation.

The third equation is the Gauss theorem about the magnetic field, which shows that the magnetic field is a vortex field (no beginning and no end) and expounds the continuity of the magnetic field.

The fourth equation is about Maxwell's magnetic field loop theorem after adding the concept of displacement current, which describes the electromagnetic characteristics.

You can understand each theorem separately;

2. There are a lot of experimental models behind each theorem:

For example, if you know the characteristics of electricity, you can do some simple and safe experiments to describe the charge quantitatively, and you can fiddle with the electric meter.

When we understand the characteristics of magnetism, we can also use the interaction between magnets or discuss the existence of magnetic monopoles.

In the study of magnetic power generation, qualitative and quantitative synchronous experiments can be used to study, such as observing whether cutting magnetic induction lines can generate current, and studying the relationship between power generation efficiency of power plants and rotor speed of generators.

When studying electromagnetism, we can also carry out qualitative and quantitative experiments at the same time, such as placing electrified wires above a small magnetic needle to observe the swing, or at a higher level, using Faraday electromagnetic induction to quantitatively design experiments to explore the relationship between current and magnetic field.

Finally, suggestion: go deep into the experiment, don't talk empty! Try to quantify when doing experiments. (You can ask your tutor for help)
