    • MAGNETISM
      “He who controls magnetism, controls the universe.” – Diet Smith
      By: Matt Vennekotter
    • FORCES
      In our universe, the way matter communicates with each other is through forces.
      The four fundamental forces include:
      Gravity
      Electromagnetic
      The Strong Force
      Weak Force
    • Gravity
      This force acts between all masses in the universe and acts between everything.
      Einstein discovered this force first through the famous story about the apple falling on his head.
    • Electromagnetic
      This force acts between electrically charged particles. Electricity, magnetism, and light are all produced by this force.
    • The Strong Force
      This force binds neutrons and protons together in the cores of atoms and is a short range force.
    • Weak Force
      This force allows beta decay to happen which changes a neutron into a proton and electron. This allows for radiation to occur.
    • Weak Force joke
    • Magnetism
      A physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
    • Magnetic Field Lines
      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.
    • Electromagnet
      Electromagnets can be made by wrapping a wire around a metal and then putting current through the wire.
    • Naturally Magnetic Materials
      Iron
      Hematite
      Magnetite
      Ionized gases
    • Magnetic Motor
      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.
    • Rediscovering Magnetism
      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.
      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.
    • Magnetism vs. Gravity
      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.
    • Controlling the forces
      We could control the world someday by unlocking the mysteries behind every force.
