What happens if you leave a microwave on with nothing in it? Since running your microwave without anything inside may damage the magnetron
Cavity magnetron
The cavity magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities (cavity resonators). Bunches of electrons passing by the openings to the cavitie…

At first, everything is fine because the cavity, the door, the tray (or shelf) absorb the excess energy. Things will start to get hot, but it's not critical yet.
What happens if you run microwave empty?
The microwave will not explode if you accidentally ran it empty. Instead, you will notice sparks, meltdowns and finally, a damaged magnetron. This electrical component generates microwaves that get absorbed by your eatables. With nothing there, these waves will keep bouncing, overheat the microwave and finally damage the magnetron.

Boiling a cup of water in a microwave could cause it to explode. Water could be over-heated (perhaps even past boiling point), as it will just keep on heating up for a long as you've set it for. So when it is disturbed or moved, it's likely that the heat will release by erupting violently.
What happens when you turn on a microwave?
When the microwave is turned on, an electric arc spews from the tip of the graphite rod! The plasma-flame may grow quite large, and it makes a loud electrical noise (it’s the 120Hz buzz from the AC supply, causing the energy field to pulse rapidly.)
What happens when a microwave runs without water?
When a microwave runs without anything inside, or if an item contains no water molecules, the microwaves in the machine will be redirected into the magnetron. When the magnetron begins to absorb as many microwavesas it produces, it can be damaged. 438 views. ·. View upvotes.

Can running a microwave while it's empty cause damage?
Running a microwave while it is empty may cause damage to the unit. When the oven is empty none, or almost none of the microwaves are absorbed. A large amount of energy reflects around the oven chamber resulting in large standing waves that can damage the unit. 98 views.
Is it bad to run a microwave with nothing inside?
No, it’s not as bad as running your oven with nothing inside. When a microwave oven is empty, the radio waves aren’t being absorbed by food (or being absorbed by buzzing gouts of flaming plasma.) Instead the waves bounce back and forth, rapidly building up.
Does a microwave overheat?
So a lot of that energy tends to get absorbed in the magnetron tube that's also the microwave source. It will overheat if that goes on very long. It sounds (smells) like you did a little of that, but since the microwave is still working ok, I wouldn't worry about it. Obviously it's good to avoid doing that again.
