IGNOU BSc Physics - Electric and Magnetic Phenomena PHE-07

The electromagnetic force plays an important role in our life in that it is solely responsible for the structure of matter from atomic to macroscopic dimensions. Even chemical compound occurring on the earth owe their existence to electromagnetic interactions. The electrical forces govern the replication of DNA molecules and hence life on ourplanet.

Moreover, the study of electromagnetism will be useful in understanding other courses of physics, like the special theory of relativity, optics, quantum mechanics, etc.
