Fridge Magnets and Chemistry

Theres a tiger on your fridge! Lurking inside refrigerator magnets of the flat, flexible variety are magnetic-field stripes of alternating polarity. This University of Wisconsin Web site explains how fridge magnets work, shows how you can use such magnets to learn about magnetic force microscopy, and suggests experiments involving fridge magnets to model how metals and salts respond to applied stress.
