Topics in Electricity and Magnetism

1

Magnetism and Magnetic Properties

  • The first magnet was discovered nearly 5000 years ago in Magnesia.
  • The word magnet is derived from the town name Magnesia.
  • A magnet attracts small pieces of iron.
2

Electromagnetism and Electromagnets

  • Hans Christian Oersted discovered in 1819 that there is a magnetic field around every wire carrying an electric current.
  • A current-carrying cylindrical coil behaves like a magnet.
  • A cylindrical coil is called a solenoid.
3

Electric Bell

  • An electric bell is a common application of an electromagnet.
  • The main parts are a horse-shoe electromagnet, a soft iron armature, a hammer, a gong, a metallic springy strip, an adjusting screw, a switch or bell push, and a battery.
  • The armature is fixed to the metallic springy strip.
4

Electric Cells and Batteries

  • A cell is a source of electricity.
  • A cell consists of a vessel with two metal rods called electrodes and a chemical substance called electrolyte.
  • In a simple cell, the copper rod becomes the positive electrode or anode and the zinc rod becomes the negative electrode or cathode.
