Title: Why don't metal microwave ovens spark off themselves?
Post by: thedoc on 16/01/2014 14:32:29

The inner walls of a microwave oven are made of metal; so why does the oven explode when another piece of metal is placed inside it?

I thought the microwave used a magnetron to send photons of a high wavelength to cook the food--not create an electric field that in turn creates currents in the food? I realize that photons, being electromagnetic waves, are related to electric field, but there is a distinct difference, no?
