ELECTRO-MAGNETISM by Jerry B. Marion.
This chapter discusses the magnetic fields and force. It explains connection between electricity magnetism. The provides an overview of electromagnetic induction some its important applications such as generation alternating current. magnet iron consists extremely large number tiny crystalline aggregates atoms called domains, each which is individually magnetic. In magnetized iron, domains are aligned with their ν poles predominantly in same direction, thereby producing overall magnetism bar. earth’s field acts on objects causes them to align direction field. focuses produced by electric currents. earth similar that a giant bar magnet. right-hand rule for determining
