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.
(*Unless you count the magnetic fieldAinside those photons that you use to see things.)
