Micro waves are not uniform so by turning you get even heating. If you want to see the heat wave pattern you can take the turning plate out, sprinkle shred cheese on a plate and heat it briefly. It will melt in some spots and not others if you measure between the melted spots you can even calculate the speed of light using and your microwave.
Cheese is hard to clean and expensive. Just use tin foil and look at where the lights dance before the fuse blows.
(Jkjk ->>> sad feeling that maybe necessary)
It's perfectly safe as long as you remember to put some gasoline on the foil.
Can vouch, when the microwave is emitted at one point in a cubed Faraday cage the waves bounce around unevenly, turning platters, building spherical microwave ovens or putting tinfoil over your food to disrupt them are the only options for evenly cooked food.
