(N/A) Faraday made public his discovery that relative motion between a bar magnet and a wire loop produces an electric current in the loop.
The phenomenon of electromagnetic induction is not merely of theoretical interest but is of immense practical utility. Imagine a world without electricity—no electric lights,no trains,no telephones,and no computers. Electromagnetic induction is the fundamental principle behind the generation of electricity.
The pioneering experiments of Faraday and Henry led directly to the development of modern-day generators,motors,and transformers. Today's civilization owes its progress to a great extent to the discovery of electromagnetic induction.
