Only at the points it discharges the waves electrically. All the rest of the metal usually stays quite cold,... I've taken out plenty of forgotten spoons in my lifetime. ๐Ÿ˜… Hence why microwavable metal is a thing. (Like the metal rack the usualky cones with combi-ovens.) Metal is a good heatconductor though, so microwavable metal will easily get hotter than the food heating it (much like your car's metal exterior getting hotter from the sun than it's environment), yet if you microwave that metal on its own it will not heat up at all...

That's... not how heat conduction works. Something can't get hotter than the thing that's heating it. What's heating the metal is the microwave radiation.

yet if you microwave that metal on its own it will not heat up at all...

But

It does

Metal that's designed to be part of the microwave, like a rack or the walls, is designed specifically to avoid heating up. But like, a spoon by itself on the turntable will definitely get hot if you microwave it

It was simplified for ease. Metal indeed does not actually get hotter than its environment, but due to it's heat conductivity it has the ability to relay any surrounding heat when any spot gets cooled down (like when you touch it), it will transfer surrounding heat-energy to the colder spot, which it can do better than most other materials.

Either way, any spoon I ever accidentally microwaved remained quite cold tbh, though I have not tested this out over extended periods of time. Any heated food touching it will still be the main source it will draw energy from when touched, though...

I don't know how we manage to live under different laws of physics then, because I have definitely touched metal that had been in the microwave and gotten hot, and there are videos of people putting metal in the microwave showing it getting hot without sparking. Unless me, everyone I know, those guys, and all their commenters are all lying, metal will most definitely get hot in the microwave

Am I getting sharks are smoothed?

Yeah, if you look it up on Google you will find above definition, though... ๐Ÿคทโ€โ™‚๏ธ
