• Magnetic materials


  can be attracted to a magnet

  ex; iron, nickel, cobalt and steel (mixture containing vast amounts iron)
• Magnetised


  means turned into a magnet and is what magnetic materials can become as the magnets you have used were all made by magnetising magnetic materials
• Permanent magnets


  always have a magentic field and its magnetic field cannot switch off and on again
• Elctromagnets


  use elcectricity and when current is switched off, the magnetic material loses most of its magnetism
• Production of electromagnets


  wrapping a wire around a magnetic material (eg. iron).

  the wire wrapping is called a coil and the maerial in the middle of the coil is called a core.

  when the current passes through the coil, the magnetic material becomes magnetised.
