Our transcription: In the Nineteenth Century it was discovered that a link exists between electricity and magnetism. English Scientist, Michael Faraday, invented a device that illustrated this principle. As an electric current is passed through wire, a magnetic field is generated. The wire moves in a circle following the shape of the field. The same principle can be observed using iron filings. An electric current generates a magnetic field causing the filings to orient themselves toward invisible north and south poles. Faraday went on to discover that moving a magnet through a coil generates an electric current. Faraday's observations are the bases of our modern views about Earth's magnetic field.
