light as an electromagnetic can travel anywhere, so does electric and magnetic field exist everywhere in space

light, electricity and magnetism is forms of energy,,,
as per law of conservation of energy energy of universe always remains constant,,,,,,,,and light doesnt require any medium to travel,,,,, even it can travel in vaccuum,,,,,, light waves can be polarised,,,,,,,,, not like sound waves which cannot be polarised,,,,,, electric field and magnetic field are mutual to each other as per oersted experiment,,,, hence it can be found anywhere in the space

No, electric and magnetic fields do not exist everywhere. But they can be anywhere.

Yes

- light is not an electromagnetic field.
- magnetic fields can exist in space.
- what kind of electric field? static electric? yes.


as for Mr science graduate kinnu, <<electric field and magnetic field are mutual to each other as per oersted experiment>> if i have a bar magnet sitting on my desk, there is a magnetic field around it. where is the electric current?

i'll be happy to grant that they CAN be mutual. but it does not seem to need to always be true.

I liked Alexandrite's answer so I voted for it : mainly on the basis that even in a solid chunk of metal there are phonon interactions between atoms and even in a faraday cage like a hollow sphere of copper, phonon exchange across the inside at any temperature. Not too sure about black holes but are they 'anywhere' anyway? What would happen in a superconducting hollow sphere? hmmm.

kennu is right

Yes!
Every electric and magnetic field extend up to infinity, only the field strength decreases drastically as we go farther from the "source", so much so that it becomes practically zero after some distance. So, all electric and magnetic fields created by all source are extending into space up to infinity.
