There is an aperture (which is not metal) for the microwaves to enter the oven.
Try a cup full of water (to protect the magnetron) and an old CD or DVD disc. Pretty sparklies.

The important thing is not to put any metal into the microwave, that has a hole, or (same thing) china that has a metalized ring all the way around its outer edge.
You can put a spoon in there and it will do nothing (except in a cup with liquid, it will keep it from overflowing, because it distributes the heat!)

Metal surfaces reflect microwaves, so microwave ovens are designed to reflect power from their own surfaces to maximize focus of the energy into the food in the middle of the oven.
If you read the book that came with your microwave, you CAN put metal in the oven if you follow the manufacturer's guidance...
(in fact if you cook a whole chicken in a microwave, you generally need to put aluminium foil on the 'pointy' bits to prevent them bursting into flames!)

Its a good question and I dont know. May I recommend the site 'how stuff works' - if you put in a microwave on their internal search you'll get a better description of anything that would be posted in here. regards.

Find "Brainiac" on TV, G4 network I think. They won't tell you why not to put things in the microwave, but they will show you what happens when you do.
Things they have microwaved:
soap (it foams up)
smoking toothpick (forms plasma arcs)
CD (sparks)
Oxygen balloon with foil strip (Boom)
dynamite with something to light it (Boom)
