Microwave Generators

Latley I have been thinking about how microwaves work and what is actually hapening inside a microwave. For those of you who are curious...

The radio waves are made by the North and South Pole magnets. Now about the magnet size.You know sunlight can go through glass, paper and leaves, but it cannot go through wood, rock and iron, but the magnets can go through everything. This shows that each magnet is smaller than each particle of light.

  1. 'but the magnets can go through everything'

    What about lead?

  2. depends on the thickness of the lead and the strength of the permanent magnet, doesn't it?
