Magnetism

  1. 1. MAGNETISM<br />“He who controls magnetism, controls the universe.” – Diet Smith<br />By: Matt Vennekotter<br />
  2. 2. FORCES<br />In our universe, the way matter communicates with each other is through forces.<br />The four fundamental forces include:<br />Gravity <br />Electromagnetic<br />The Strong Force<br />Weak Force<br />
  3. 3. Gravity<br />This force acts between all masses in the universe and acts between everything.<br />Einstein discovered this force first through the famous story about the apple falling on his head.<br />
  4. 4. Electromagnetic<br />This force acts between electrically charged particles. Electricity, magnetism, and light are all produced by this force.<br />
  5. 5. The Strong Force<br />This force binds neutrons and protons together in the cores of atoms and is a short range force. <br />
  6. 6. Weak Force<br />This force allows beta decay to happen which changes a neutron into a proton and electron. This allows for radiation to occur.<br />
  7. 7. Weak Force joke<br />
  8. 8. Magnetism<br />A physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.<br />
  9. 9. Magnetic Field Lines<br />Michael Faraday called the lines you see “lines of force” but was changed to field lines. This helps describe the direction of the force on a magnet.<br />
  10. 10. Electromagnet<br />Electromagnets can be made by wrapping a wire around a metal and then putting current through the wire.<br />
  11. 11. Naturally Magnetic Materials<br />Iron<br />Hematite<br />Magnetite<br />Ionized gases<br />
  12. 12. Magnetic Motor<br />Magnetic motors can be used to turn electrical energy into a rotation and is used nearly everywhere. When the electrons flow through the wire it attracts the magnets causing them to spin.<br />
  13. 13. Rediscovering Magnetism<br />Gravity is a force. It has an infinite range which means it occurs between all matter. It is only noticed when we think between two big objects.<br />Magnetism is a force. Books say it does not have an infinite range. Just because we cannot see it between two objects does not mean there is no magnetism between all matter.<br />
  14. 14. Magnetism vs. Gravity<br />Magnetism can make objects attract each other and repel while gravity is only seen as the attraction of two objects. Personally I think gravity is a part of magnetism. <br />
  15. 15. Controlling the forces<br />We could control the world someday by unlocking the mysteries behind every force.<br />
