Electrical engineer, the answer is simple. The metal box is a conductive plane, preventing potential differences from accumulating. They discharge naturally and rapidlly The frequency of the microwaves are set up to create a standing wave in the microwave.
The Short Answer
Electrical engineer, the answer is simple. The metal box is a conductive plane, preventing potential differences from accumulating. They discharge naturally and rapidlly The frequency of the microwaves are set up to create a standing wave in the microwave. This standing wave is caused because the electrically conductive box is the right size to do so. If a metal object is in the microwave and shaped so that there exists a potential due to standing waves that cannot be discharges over the metal, it will likely amplify until it arcs. So, what causes this potential and thus arc? 1. Two bits of metal which are close but not in contact. Take two strips of aluminium foil, bend in zig zags and place close, but not touching in a microwave, they should go off nicely. 2. Sharp points in close proximity with a long conductive distance between them. Fork tines are good for this. A screwed up bit of foil also works. And if you want to watch something cool, try a CD, that goes off like a firework due to #1.
