How do moving electric fields create magnetic fields?

[Yuqing]

I have a bit of trouble with understanding how electromagnetic fields. More specifically, how the magnetic and the electric component of the field interact. I am aware that a time-varying electric field will generate a magnetic field and vice versa. What I am having trouble understanding is how it manages to do so. How does a moving electric field suddenly become a magnetic field? I've tried to work it out from the equations but I'm having trouble understanding them. If anyone can point me in the right direction it would be greatly appreciated.

a moving electric field does NOT become a magnetic field, it produces one due to magnetic flux.

It's rather difficult to explain, so here are some links that might help:

I hope this helps!

I can provide an explanation for how moving electric fields create magnetic fields. It is based on the fundamental principles of electromagnetism, which describe the relationship between electric and magnetic fields.

Firstly, it is important to understand that electric fields and magnetic fields are interconnected and cannot exist without each other. When there is a change in an electric field, it creates a magnetic field and vice versa. This is known as electromagnetic induction.

In simple terms, when a charged particle moves, it creates an electric field around it. This electric field, in turn, creates a magnetic field that is perpendicular to the direction of the electric field and the direction of motion of the charged particle. This is known as the right-hand rule, where the thumb represents the direction of motion, the index finger represents the direction of the electric field, and the middle finger represents the direction of the magnetic field.

Now, when there is a change in the velocity or direction of the charged particle, the electric field also changes, resulting in a change in the magnetic field. This change in the magnetic field then creates an electric field, and the cycle continues. This is how a moving electric field creates a magnetic field.

To understand this concept mathematically, we can use Maxwell's equations, which describe the relationship between electric and magnetic fields. These equations show that a time-varying electric field (caused by a moving charged particle) induces a magnetic field, and a time-varying magnetic field induces an electric field.

In summary, the interaction between electric and magnetic fields is a fundamental principle of electromagnetism. A moving electric field creates a magnetic field through electromagnetic induction, and the two fields are interconnected and continuously influence each other. I hope this explanation helps in understanding the concept better.
