5 magnetism

  1. 1. Magnetism
  2. 2. <ul><li>Magnetism - the properties and interactions of magnets. </li></ul><ul><li>-All magnets have a north and south pole. </li></ul><ul><li>North Pole to South Pole = attract </li></ul><ul><li>North Pole to North Pole = repel </li></ul><ul><li>South Pole to South Pole = repel </li></ul>
  3. 3. <ul><li>Magnetic force- The interaction between 2 magnets. Its strength increases as magnets move closer together and decreases as they move apart. </li></ul>
  4. 4. <ul><li>Magnetic poles- regions where the magnetic force exerted by the magnet are the strongest. </li></ul><ul><li>- Earth’s magnetic pole= Earth has a imaginary bar magnet going through it with its south magnetic pole near the geographic north pole. That’s why a compass always points north. </li></ul>
  5. 6. <ul><li>Magnetic domains- group of atoms with aligned magnetic poles. </li></ul><ul><li>Ex: iron, nickel and cobalt domains will align themselves along a magnet. </li></ul>
  6. 7. Unmagnetized Magnetized
  7. 8. <ul><li>Permanent magnets are object made from a material that is magnetized and creates its own persistent magnetic field. </li></ul>
  8. 9. <ul><li>Temporary magnets are those which act like a permanent magnet when they are within a strong magnetic field, but lose their magnetism when the magnetic field disappears. </li></ul>
  9. 10. <ul><li>You can find them in Kiruna in Switzerland and many other European countries. </li></ul><ul><li>You can find them in Norway, Germany and Italy. There are some other places also where you can find magnetite and the places are mostly located in the United States. It can be found it in the states of Oregon, New Jersey, Pennsylvania, North Carolina, Virginia, New Mexico, Utah and Colorado.  You can also found the mineral in countries like India and South Africa. When you are in the US state of California you can find magnetite on some beaches also and this phenomenon happens on the western coast of New Zealand too. </li></ul>
