How charged particle got to do with magnetism

Click For Summary
SUMMARY

The discussion centers on the relationship between charged particles and magnetism, specifically how moving electrically charged particles, such as electrons, generate magnetic fields. It is established that magnetism arises from the movement of charges, which creates an electromagnetic (EM) field. The conversation highlights that a current-carrying wire produces a magnetic field due to the movement of electrons, and a changing electric field can induce a magnetic field. This fundamental principle underpins many applications in electromagnetism.

hello, I am not too sure of how charged particle got to do with magnetism.

"Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field, which is caused by moving electrically charged particles or is inherent in magnetic objects such as a magnet." (form http://www.school-for-champions.com/science/magnetism.htm)
do charge particles means electron and it is their electron sub shell that causes the effect of magnetism? Is that also why current produces a magnetic field? would like some explanation!

THX!

your question is kind of hard to answer , at least for me because it is so fundamental.
But a current carrying wire has an EM field because the charge is moving . your asking
why moving charges creates magnetism , The electron has an electric field and when this E field changes it creates a magnetic field , I don’t know it this will answer your question . So a changing E field can create a magnetic field.
