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.
