magnets [1] [video clips] [appearing pictures with notes]

• 1. These are screenshots taken from the video clip to help you understand magnetism.
  • 
• 2. Magnets are all around us, an example would be fridge magnets holding pictures in place.
  • 
• 3. Magnets are able to produce a magnetic field that can attract some other metals.
  • 
• 4. Those other metals are iron, nickel and cobalt.
  • 
• 5. A magnet will only attract paper clips from seeds, paper and rubber bands.
  • 
• 6. Magnetism is the ability to attract iron objects without even touching them.
  • 
• 7. The closer the objects are to the magnet the stronger the magnetic force.
  • 
• 8. The closer two magnets are together the stronger the magnetic pull.
  • 
• 9. All magnets have a north [N] and a south pole [S]. Poles are the strongest parts.
  • 
• 10. A north pole [N] and south pole [S] will attract and pull together.
  • 
• 11. Whereas two north poles [N] or two south poles [S] will repel each other.
  • 
• 12. Magnets are made of metals that have been exposed to a very strong magnetic fields.
  • 
• 13. A magnetic field is the area around the magnet creating the north/south pattern.
  • 
• 14. Earth's north and south poles are where the magnetic pulling force is the strongest.
  • 
• 15. That's why a compass needle is always attracted to earth's north pole.
  • 
• 16. We use magnets in many ways, like to get a tight seal on your refrigerator door
  • 
• 17. Or in your mobile phone, in your laptop and in your sound speakers..
  • 
• 18. The metal strip on the back of a credit card is magnetic too.
  • 
• 19. Magnets are also used in medicine for machines like magnetic resonance imaging [MRI].
  • 
• 20. Magnet are used in recycling, separating the iron from the glass and paper.
  • 
• 21. So to recap, the ability to attract objects made of iron is called magnetism
  • 
• 22. A magnet is made from metals such as iron, nickel or cobalt.
  • 
• 23. Around the magnet is a magnetic field.
  • 
• 24. This field has forces that can attract or repel depending upon the poles.
  • 
• 25. The poles are the strongest parts of the magnet.
  • 
• 26. This final picture is a collection of all the pictures used in this video on magnetism.
