I was about to do an experiment in Wolfram Mathematica like drawing electric field lines around a charged body and other arrangements. So i saw this nifty little Function for that very purpose called VectorPlot(adsbygoogle = window.adsbygoogle || []).push({});

My Problem is that i dont know what the function does exactly i went through examples in the Wolfram Mathematica documentation but it did not mean anything to me.

I Read This Article : http://mathworld.wolfram.com/VectorField.html

All i saw was that vector field meant something about the x axis and some function on it

My Questions Are:

How Exactly are those small vector lines represented ?

Like In this Example where I was playing with the Function

http://puu.sh/pxch [Broken]

what is happening to the x and y and what is making the vector lines change Size?

What is Giving it direction?

Is there an equation that is defining the vectors.?

Could any one explain this to me....Please......BTW im a high school student so can you explain it in a way that is undergrad level...
