In this chapter, we will study the
phenomena associated with changing magnetic fields and understand
the underlying principles The phenomenon in which electric current is
generated by varying magnetic fields is appropriately called
electromagnetic induction When Faraday first made public his discovery that relative motion
between a bar magnet and a wire loop produced a small current in the
latter, he was asked, “What is the use of it ” His reply was: “What is the
use of a new born baby
