# What do curl/Dovergence of various fields represent?

jsut wondering, is there any realistic OR theoretical significance to:

$$Div \stackrel{\rightarrow}{G}$$
$$Div \stackrel{\rightarrow}{E}$$
$$Div \stackrel{\rightarrow}{B}$$
$$Curl \stackrel{\rightarrow}{G}$$
$$Curl \stackrel{\rightarrow}{E}$$
$$Curl \stackrel{\rightarrow}{B}$$

where $$\stackrel{\rightarrow}{G}$$, $$\stackrel{\rightarrow}{E}$$ and $$\stackrel{\rightarrow}{B}$$ are a gravitational, electric, and magnetic field respectivley.

Thanks

Looks like a homework question. What do you think the answers are? You need to make an attempt.

Loosely speaking, 'divergence' is a measure of the sources and sinks to a field. 'Curl' is a measure of the rotation.

No, it is not a homework question. Im just studying for finals and I have calculus and physics left...so a lot of these kind of questions have been going through my head. We talked a little about it in math, something to do with the field being conservative (havent gotten that far in my studying yet).
And from physics gravitational and electrical fields are conservative...but I just dont know what the exact correlations between the 2 are and was wondering if there was one.

i wish someone would've helped me with this, it showed up on the final I was studying for. =\
