I am drawing a tikz diagram of a circle with equally spaced field flow lines flowing around it, starting from below, up, around, then up. I was not able to find a post that was helpful for this one. I've tried using \draw..controls which allows curved paths using control points, for Bezier curves. My difficulty is that it only allows two control points, so flowing around something like a cirlce seems impossible. Too much distance between points and it goes thru it. Too little, then it can't go all the way around. I'd love to figure out a way to do this. Any ideas to draw equally spaced flow lines around a circle? Thanks. An minimum working example code is below, although I'm not sure where this should go. Thx again.
\begin{tikzpicture}
\filldraw [black,fill=gray] (3,0) circle (1);
\draw[->] (2.5, -2.0) .. controls (2.5,-1.2) and (2.25,-1.0) .. (0.8,0);
\draw[->] (2.3, -2.0) .. controls (2.3,-1.2) and (2.05,-1.0) .. (0.6,0);
\end{tikzpicture}
Per the suggestion, I've added an image...a pretty bad one, but hopefully it still helps to show what I would like to do. Thx again!
