Magnesium

  1. 1. Magnetism
  2. 2. A substance which attracts iron particles/objects is called Magnet. In addition to iron , Magnet also attracts Nickel and Cobalt. Property of Magnet to attract specific metals is called Magnetism. Magnetic force works even without being in contact with the object. Magnetism
  3. 3. The existence of magnet was first discovered in Magnesia, a Village in Asian Continent. A shepherd named Magnes, realised that his shoes and iron nails attached to his stick are getting pulled towards a specific stone. This stone, one of the natural minerals, having magnetic properties AyaskaMt Kinaja is also called as Loadstone in Middle English. After further research various different types of magnets were discovered. Discovery of Magnet Magnetism
  4. 4. Types of Magnets Disc Magnet Magnetic Compass Bar Magnet Horse-shoe Magnet Magnetism
  5. 5. Magnetism
  6. 6. Magnetism
  7. 7. Magnetic Substances Those substances which are attracted towards magnet are called as Magnetic Substances Non-Magnetic Substances Those substances which does not get attracted towards Magnet are called as Non-Magnetic substances. Magnetism
  8. 8. Magnetism
  9. 9. Properties of Magnet The edges of Magnet are called it’s Poles. A freely suspended magnet , parallel to horizon comes to rest in North- South direction. The edge pointing towards south is called South Pole whereas the one pointing towards North is called North Pole. Magnetism
  10. 10. Magnet’s strength is located at it’s poles. Magnetism
  11. 11. A magnet repels the like pole of the other magnet. (South-South/North-North) Magnetism
  12. 12. Magnetism
  13. 13. There is attraction between unlike poles of two magnets. Magnetism
  14. 14. Earth itself is a huge Magnet. But it’s geographic poles are exactly opposite of Magnetic poles. i.e Earth’s geographic North Pole = Earth’s Magnetic South Pole Earth’s geographic South Pole = Earth’s Magnetic North Pole Magnetism
