Electromagnetism is a branch of physics which involves the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The electromagnetic force usually shows electromagnetic fields, such as electric fields, magnetic fields, and light. The electromagnetic force is one of the four fundamental interactions in nature. The other three fundamental interactions are the strong interaction, the weak interaction, and gravitation.
The word electromagnetism is a compound form of two Greek terms, ἤλεκτρον, ēlektron, "amber", and μαγνῆτις λίθος magnētis lithos, which means "magnesian stone", a type of iron ore. The science of electromagnetic phenomena is defined in terms of the electromagnetic force, sometimes called the Lorentz force, which includes both electricity and magnetism as elements of one phenomenon.
The electromagnetic force plays a major role in determining the internal properties of most objects encountered in daily life. Ordinary matter takes its form as a result of intermolecular forces between individual molecules in matter. Electrons are bound by electromagnetic wave mechanics into orbitals around atomic nuclei to form atoms, which are the building blocks of molecules. This governs the processes involved in chemistry, which arise from interactions between the electrons of neighboring atoms, which are in turn determined by the interaction between electromagnetic force and the momentum of the electrons.

i'm a modern man looking for modern love
cookieookienookie
is all that i'm thinking of
got a hot little number flashing on my screen
think i'll leave a little message
on her answering machine
emotion's out of style
we got something stronger
electromagnetism
all this love n affection just leaves me cold
you know a heart of steel
will always beat a heart of gold
n when it's all said and done
i can forget the name
although the software's different
the current feels the same
emotion's out of style
we got something stronger
electromagnetism
some nights i lay awake and wonder
about these feelings i've never known
so many people at my fingertips
tell me
why am i alone?
