MAGNETS AND MAGNETIC MATERIALS

  1. 1. ABOUT MAGNETS www.sciencetutors.zoomshare.com
  2. 2. MAGNETS OBJECTIVES <ul><li>To know that some materials are magnetic and others are non-magnetic. </li></ul><ul><li>To know that like poles of a magnet repel while unlike poles of a magnet attract. </li></ul>S N N N S
  3. 3. ALL ABOUT MAGNETS Look at the pile of rubbish. Your task is to list which bits (of rubbish) can be picked up with a magnet for recycling. www.sciencetutors.zoomshare.com www.sciencetutors.zoomshare.com
  4. 4. ALL ABOUT MAGNETS Look at the pile of rubbish. Your task is to list bits (of rubbish) which cannot be picked up with a magnet for recycling. And explain why? www.sciencetutors.zoomshare.com www.sciencetutors.zoomshare.com
  5. 5. MAGNETIC OR NON-MAGNETIC? LOOK AT LETTERS A-D and Discuss. A B D C
  6. 6. POLES OF A MAGNET <ul><li>Suggest practical ways of verifying the Poles of a Magnet. </li></ul>
  7. 7. REPULSION AND ATTRACTION <ul><li>Write a complete sentence using the following keywords: </li></ul><ul><li>Attraction </li></ul><ul><li>Repulsion </li></ul><ul><li>Like poles </li></ul><ul><li>Unlike poles </li></ul>S N S N N S N S TASK II TASK 1 Which of these bar magnets will attract each other and which pair will repel? And why? Copyright © Ivan @ Science tutors 2006 www.sciencetutors.zoomshare.com
  8. 8. Demonstrate magnets in slings for attraction/repulsion. <ul><li>Prediction : Make a prediction for this practical activity. </li></ul>
  9. 9. MAGNETIC MATERIALS AND MAGNETS <ul><li>Distinguish between Magnetic materials and Magnets. </li></ul><ul><li>A magnet is a material or object that produces a magnetic field and is able to attract or repel. </li></ul><ul><li>All magnetic materials are affected by magnetism, but they do not repel like magnets. </li></ul>www.sciencetutors.zoomshare.com
  10. 10. PRACTICAL ACTIVITY <ul><li>Demonstrate all magnetic materials attracted but only magnets repelled. </li></ul><ul><li>Equipment </li></ul><ul><li>Sample of magnet / non-magnetic materials in sets of 8-10. </li></ul><ul><li>8-10 magnets </li></ul>
  11. 11. REPU LSION TEST FOR MAG NETS <ul><li>OBJECTIVE </li></ul><ul><li>To understand that repulsion is used to test whether or not an object is a magnet. </li></ul>
  12. 12. LEVELS 5-7 HOMEWORK <ul><li>Draw a bar magnet showing north and south poles. Use your diagram to answer the following questions </li></ul><ul><li>Where is the magnetism strongest? Put an X. </li></ul><ul><li>Explain why magnetic effect or magnetism is strongest at point X as shown by your diagram. </li></ul><ul><li>Draw a diagram showing the field lines around a bar magnet. What are magnetic field lines? </li></ul>
  13. 13. LEVELS 3-4 HOMEWORK <ul><li>Recognise that both magnets and the Earth have magnetic field lines. </li></ul><ul><li>Draw a diagram showing the field lines around a bar magnet. </li></ul><ul><li>What are magnetic field lines? </li></ul>
