Moving electric charges generate a magnetic field. This isn't a theory, it's a simple demonstrable fact. There really isn't a theory why this is true, it's just something that istrue.
"Spinning" charges also generate a magnetic field. I've got "spinning" in quotation marks because this applies also to charges that aren't actually physically spinning, but have a non-zero quantum spin number.

Do you mean "can current flow in both directions"? In theory, yes.
The origin of that picture is unknown.
in series you XL, voltage leads the current, and in Parallel current leads the voltage. so your answer should reflect on this theory.

The current ring theory of magnetism suggests that magnetic materials possess microscopic "current loops" created by the movement of electrons within the material. These current loops produce magnetic fields and are responsible for the magnetic properties observed in materials.
Current theory is that the mechanism for field generation is the "geodynamo". The outer core rotates and conducts energy.
The foundation of magnetism is described by the magnetic field theory, which explains how magnets create magnetic fields that attract or repel other magnets or magnetic materials. This theory is based on the concept of magnetic fields being generated by the movement of electric charges within atoms and molecules.

According to photon theory ,electromagnetic radiation consists of photon which are changeless particles. therefore they are not deflected by electric or magnetic fields.
The finding that electric current can produce magnetic field (Oersted Theory) that leds to idea that magnetic field should also produce electric current (Faraday Theory). I . xD -JMiko Andres Benjamin B. Esguerra Memorial National High School

The curl of the electric field in electromagnetic theory indicates the presence of changing magnetic fields. This relationship is described by Maxwell's equations and is crucial for understanding how electric and magnetic fields interact and propagate as electromagnetic waves.
That's what the current theory indicates.
Tesla was a very important scientist and he said the magnetic field theory. It was a very significant theory and today we all know about the magnetic fields. A pop band has also used this name too.
There are two theories that are used to explain magnetic therapy. One theory maintains that magnets produce a slight electrical current.
