Evil Mad Scientist Laboratories, start seeing magnetic fields

Magnetic fields are everywhere– you just can’t see them*. Here we introduce some basic and inexpensive visual tools, as varied as iron filings and Arduino, pre-school toys and OpenGL, for getting to know your local fields. It’s not exhaustive, but might provide you with some useful starting points for your own exploration.
