@Shing:Well, shouldn't it be based on something we intuitively understand?

I can understand that there are various teaching approaches, but aren't 100% of textbooks the same way as wiki presents the definition? How can it be understood if the actual experiment steps are presented much later or omitted?

@Hurkyl:Yes, but words is to explain and pass an idea. They are not for decoration.

comment Intuitive definition of electromagnetic field
I am a bit confused about your answer. If definitions in physics essentially describe experiments, then why are they presented as definitions instead of presenting the experiment steps and what the conclusion is? I mean the pre-requisite to understand the "definition" is to be familiar with the experiment (whose effect is being described) in the first place, right?

comment Intuitive definition of electromagnetic field
The way you phrase it placing it within the general statement/rule that each action has a reaction really makes a difference in understanding the statement. Some how when I read the statement I could not understand it that way. To be honest before reading what you note to cause such forces you have to be responsive to such forces. I understood that the definition in the wiki was nonsensical like saying: "Red is something that is of red color"

The core point of this, is that he claims that an inisignificant action such as the current passing from the wire (from the batery) will have a side-effect which is "broadcasted" into a distance which is disproportionally larger than the action itself (just a small current from a battery). It seems correct in a "gross" way from your answer and of Cris
