How microwave oven works?
In microwave ovens, the two important things are presence of water molecules in the respective food stuff and the production of microwaves.The microwave acts like a magnetic field while the water molecules are compared to a magnetic dipole placed in a magnetic field.We know that when a magnetic dipole is placed in a magnetic field, it produces some torque.
Similarly when microwave is passed through the food stuff, the water molecules in the stuff reacts to release some energy, which is acquired by other particles in the food stuff leads to cooking of the food.

In the fig. the green lines indicates the microwaves, thus the watermolecules reacting to it.
