• • Thats very intuitive. So when some vecotor quantity signify curl, its direction implies axis of rotation, being counterclockwise if the value turns out positive and cloclwise if the value turns out negative. So does the magnitude imply its itensity.
For instance, suppose we have curl = (ai+bi+ck), direction simply implies the axis about which it is rotating, and what does the magnitude √a²+b²+c² imply.
since the vecotr looks like any old position vector, is there some symbolic representaion implicitly defining that the vector is the curl, and not any other forms of vector like position vector, or a gradient vector, or a field vector.
