Would electromagnetic waves exist if changing magnetic fields could produce electric fields but chaning electric fields could not in turn produce magnetic fields?
no
When electric and magnetic fields both exist it is called an?
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to fluxuate in phase at a harmonized frequency.

Why light can pass through empty space?
Basically, light is NOT a mechanical wave, which would require matter; it is an electromagnetic wave, which means that disturbances in the electric field and the magnetic field propagate. This requires no matter; such fields exist - and can propagate - in empty space.

When and magnetic fields exist its called an electromagnetic field?
A temporary magnetic field created by a flowing electrical current is an electromagnetic field. Stop the current from flowing, it goes away.

How an electromagnetic wave can travel throught space that contains no matter?
The wave is a disturbance in the electric and magnetic field in space. These fields exist even in empty space.
Do electric and magnetic lines of force physically exist?
The "lines" of latitude, longitude, reasoning, electric fields, and magnetic fields are imaginary.
What fields gravational magnetic or electric can only exist in one direction?
gravitational
Why can light travel through a vacumn?
That is because light is not an atom bumbing into the next atom (as in a sound wave), but changes in the electrical and magnetic fields. These can exist in empty space.That is because light is not an atom bumbing into the next atom (as in a sound wave), but changes in the electrical and magnetic fields.

Do electric and magnetic fields always form closed loops?
Magnetic fields do, because there's no such thing as an isolated magnetic "pole", and a magnetic line always starts and ends at opposite poles of the same magnetized object. But electric fields don't. You can easily have a bundle of isolated positive charge over here and a bundle of isolated negative charge over there, whereupon the lines of the electric field start on one bundle and end on the other bundle. But electric field lines can also exist in closed loops, and they do that in radio waves, where the electromagnetic field propagates with an electric field component and a magnetic field component, and they both form closed loops.
