The microwave shoots particle waves called micro-waves (hence the name) and those invisible waves are sent from the microwave into the food (or other item in the microwave) and when those particle hit the food, they disturb the food particles, mostly the water in the food, and when particle are disturbed (moved) it generates heat. Therefore while the waves are hitting the food, it will get hotter and hotter.
This explains why when you put really frozen, large chunks of food like potatoes, it takes a while to warm up, because potatoes have a lot of water in them, it takes more micro-waves to heat it than an object with less.
Hope this helps!

In a microwave, electrical energy from the power source is converted into electromagnetic waves (microwaves) which in turn generate heat energy by causing water molecules in food to vibrate and produce heat. So, the energy transformation in a microwave involves conversion from electrical energy to electromagnetic waves and then to heat energy.
When you warm up a cup of cocoa in a microwave oven, electrical energy is converted to electromagnetic radiation (microwaves) to heat up the water molecules in the cocoa. The absorbed radiation energy is then converted to thermal energy, raising the temperature of the cocoa.
The energy transformation that takes place is the conversion of one form of energy to another, such as kinetic energy to thermal energy, electrical energy to light energy, or chemical energy to mechanical energy. This conversion is governed by the laws of thermodynamics and is essential for all processes and activities in the universe.
Electrical to mechanical energy conversion takes place in a motor. The motor uses electricity to generate rotational motion, which can then be used to drive various mechanical systems.
In a handwarmer, the energy conversion takes place from chemical energy to thermal energy. This occurs when the chemicals in the handwarmer react and produce heat, which then warms up the surrounding environment.
