Magnetism


Magnet










  • Magnets are objects that produce an area of magnetic force called "magnetic field" which is invisible to the human eye.
  • Most metals are not attracted to magnets. The metals that are attracted to magnets are iron, nickel and cobalt. Steel is a mixture of metal because it
    contains iron.
  • All magnets have two poles.
  • Two magnets with different poles will attract each other
