Hysteresis
Here is an animation (thanks to Chris Pelkie, Cornell Visualization Service.) of the avalanches in a 3D model magnet, near the disorder and field where the infinite avalanche first appears.

Hysteresis and Avalanches
Physicists in the US usually hear about hysteresis first in their sophomore or junior year. The magnetization of the tape lags behind the field from the tape head - so when the field drops to zero, the tape stays magnetized, storing the music.
