The steering coils are simply copper windings (see How Electromagnets Work for details on coils). These coils are able to create magnetic fields inside the tube, and the electron beam responds to the fields. One set of coils creates a magnetic field that moves the electron beam vertically, while another set moves the beam horizontally. By controlling the voltages in the coils, you can position the electron beam at any point on the screen.
The coils themselves can be done with a just a rattail comb (or even your fingers) and your favorite styling pudding or pomade. You can wear your coils and subsequent coil-out for a few days to a week at a time. Even better, a coil out looks great on many hair lengths, whether you’re rocking a TWA or longer curls.
