I want to find good pop music. Help me please.

It’s not necessarily going to cause problems (though I wouldn’t try it!).

The reason that microwaving metal objects can be a bad idea is that the electromagnetic wave used to transmit energy into your food creates potential differences across the surface. Because metal is a conductor, this results in current flowing through the object as electrons move to neutralise the potential difference.

If your object has poor conductivity (eg. if it is thin) this will result in large amounts of heat, which can damage the metal object, your microwave, or (most ghastly of all) your dinner! Metal objects that converge into points can result in relatively close areas of different potential being separated by air. Sparks will fly as electrons bridge air gaps to equalise potential.

Cast iron pots are relatively conductive and don’t converge to points, so should safe in a microwave.

Conductive surfaces also reflect electromagnetic waves. This will prevent your food from being heated if you leave the lid on your pot – also, if there is nothing to absorb microwaves while the unit is being operated, you will eventually cause damage to the magnetron.
