The way microwaves work is through jiggling charged/polar particles in your food (the water primarily). This jiggling increases their temperature and that heats up the rest of your food. That's why you can't heat oil as easily as you can water.

The Short Answer

The way microwaves work is through jiggling charged/polar particles in your food (the water primarily). This jiggling increases their temperature and that heats up the rest of your food. That's why you can't heat oil as easily as you can water. However, metals like iron are *great* conductors of electrons. What makes them good conductors is a little complicated but basically, the reason is that they have a soup of electrons moving from atom to atom with almost 0 energy needed to move an electron from one atom to another. Thus when the microwave jiggles these electrons, rather than giving energy to the atom, it gives it to the electron which zips around in the soup. The amount of energy given to the soup can get high enough to bypass the natural insulation of the air and cause electrons to jump from the metal and rip through the air. This is called a spark and is basically what happens during a lightning strike.
