electromagnetics

Hi,

Electromagnetism is one of the four fundamental interactions of nature. It is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields.

Electromagnetism is the force responsible for practically all the phenomena encountered in daily life (with the exception of gravity). This includes the forces we experience in "pushing" or "pulling" ordinary material objects (such as coffee cups), which come from the intermolecular forces between the individual molecules in our bodies and those in the objects. These in turn result from the forces involved in interactions between atoms, which themselves can be traced to electromagnetism acting on the electrically charged protons and electrons inside the atoms.
