I know electric field is caused when ever there is a Charged Particle

And Magnetic Field is created arround a Magnet

Gravitational field is created arround a Mass.

I heard Gravitational field is caused by Gravitons?

Electric field by Protons & Electrons.

Magnetic Field by XXXXX?

When ever a Charge is moving it produces Electric Field and a Magnetic
Field Perpendicular to the direction of this movement.

Why this Magnetic Field is Caused? When a Charge particle moves.

I am interested in the Elementry particle that Causes the force of
Electric Field & Magnetic Field.

So when an Electron is moving It creates Magnetic Field, Electric
Field and Gravitational Field.

I understand Gravitational Field of Electron as Electrons are throwing
Gravitons But why is Magnetic Field & Electric field occur in a moving
electron.

And how far does the electric/ Magnetic & Gravitational field are
seen?

If an Electron is 1 lightyear away from us

Actually, a magnetic field is created either around a current or in
the midst of a changing electric field.

(Now, the next question the hobbyist will rightfully ask is, which of
these is a Magnet?)

No, not caused by. Mediated by.

Electromagnetic field is caused by electrically charged particles.
Protons and electrons are stable charged particles. The field is
mediated by photons.

Every attempt at a quantum-like theory of gravitation has led to grief
and unsuccess so far. There is no a priori reason for gravitation to be
like electromagnetism.

Yes. Each charged particle has an electric field associated with it.

At the macroscopic level, yes.

There is gravitational attraction between masses.

This is hypothetical. Never proven to be true.

Each charged particle can be located at the center
of the fields that it is associated with.

The magnetic field is associated with the spin of
charged particles. Ref: CRD handbook of Chemistry and Physics.

Absolutely. Which is a manifestation of their magnetic field, as
clearly explained in the CRC Handbook section 12, page 126
in the 2003-2004 edition.
