EXPERIMENT MAGNET

 MAGNET

In everyday life we ​​are always close to the magnet. Earth where we live is a giant magnet , our bodies and objects around us a lot to have magnetic properties. Magnetic strength is highly dependent on the source, and the area around the magnet is called the magnetic field source.
       The magnetic field has the power to attract or reject materials / objects that have the nature of magnetism. Magnetization properties of materials are often easily measured by whether or not a material is influenced by magnetic fields. This magnetic field appears on a current-carrying conductor. Flow time-varying magnetic field will induce a time-varying electric fields and cause induction. So the nature of magnetism and electricity and going back and forth as the cause and effect, and is often named as electromagnetic fields.
      The application of a magnetic field and electromagnetic fields has been very widely used in many fields, such as medicine, engineering, transport, communications and computer harware.



How Magnet Interaction occurs

     Over hundreds of years, we know the usefulness of magnets. Some objects respond to a given magnetic force, or interested in, but there are not affected. What are the things that can be affected by magnets?

 Tools and Materials
• A bar magnet
• tacks
• A pencil
• An eraser
• A sheet of paper
• Knives
• Lock
• Coins
• Fabric former
• Comb
• Equipment aluminum
• A piece of tape marks

 Experimental Procedure
Magnet touch to each item. Any item that attracted and attached bar magnet? Any item that is not attracted by a magnet?

 
Discussion
Do you find that the only thing that comes from the iron and steel are attracted to a magnet? Apparently magnet also attracts cobalt and nickel. Generally magnet made of iron and steel, is also usually mixed with other materials such as cobalt and nickel. But some magnets made of plastic and ceramic powder mixed with magnets.
