E-Field Attenuation: Causes & Effects

[Apteronotus]

Do electric fields attenuate in space?

If so what causes the attenuation?

I am not sure what you are looking for. In general fields spread out and therefore attenuate, following an inverse square law.

When I move away from a planet farther into space, its gravitational pull on me decreases right?

Would you say that the gravitational field is attenuated in space?
What would be causing this attenation?

We can visualize the strength of a field by thinking of field lines. Near the source of the field the field lines are all very dense. As the distance from the object increases the density of the field lines falls off in accordance with the inverse square law. http://en.wikipedia.org/wiki/Inverse-square_law
