One can fairly easily draw a rather neat coil around a core of one's choosing, for example like this

\documentclass{minimal}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (-1.9,.15) .. controls (-1.3,.25-0.3) and (1.3,.55) .. (1,.25);
\draw[fill=yellow] (-1,-1) rectangle (1,5 ...

Greetings!
I'm writing a lab report for a series of experiments on GaAs wafers related to dopants and dopant quantities. For the lab report it is expected to include a few diagrams and figures. I've been wanting to put a hall-bar into a set of circuit diagrams for this purpose. I want said component ...

Ah. Turns out there was a problem with my tex Live installation. It's fixed now. Thanks anyway

Thanks. Yes, that's what the manual suggested too.
But it will not compile when I type that into my document.

I'm stymied as I cannot find a way to get the text to fold and stay visible. I could let the text ...

Whoa! That was easy! Thank you VERY much!

Hello everyone. I am not new to LaTeX, but I am new to tikz. I am playing around with it today, in anticipation of a lab report on some semiconductor experiments I am running, and have made a simple 3D representation of a GaAs unit cell in tikz. However, I am uncertain about how to:

Rotate/align ...
