Hello;(adsbygoogle = window.adsbygoogle || []).push({});

I remember the days of muti variable calculus. The man said that divergence is equal to del dot the vector field. So on the exam he gave us a vector field, and I did del dot the given vector field and won big time.

The other day I decided my concentration would be electromagnetics. Now I need to know what divergence means. I understand that divergence gives you the scalar value of the source or sink at a point. Right?

It seems weird to me. That you decide the scalar value of a source or a sink at a POINT by considering the WHOLE vector field. I think I need help clearing this up.

For example, lets say I'm given a vector field A. Let's say del dot A = something. Does this mean that the vector field has a source equal to that something? At what point exactly? Is there only one source or sink?

This is the best that I can explain my troubles. I hope someone can help me. Thank you.
