  1. Magnetic Interactions Yolanda Philips Nicholai Aarons

  2. 3 Main Subtopics • What is Magnetism? • Types of Magnets • Everyday Uses Of Magnets

  3. What is Magnetism? • Magnetism is a force that causes attraction or repulsion between objects. • Magnets always contain metal. • The atoms in a magnetic material, like iron or steel, all point in the same direction. • Magnetic force can travel through many materials, even water.

  4. What is Magnetism? • Magnets attract only certain types of materials which are: steel, iron, cobalt, and nickel. • Every magnet has two poles. • The poles are the points where the magnetic force is strongest. • One pole is called the north pole. • The other is the south pole.

  5. What is Magnetism? • The area around a magnet is called the magnetic field. • Magnetic fields are invisible. • A magnetic field is created by the magnetism of a permanent magnet, or electromagnet.

  6. Types of Magnets • There are different types of magnets. • Permanent • Temporary • Electromagnets • Magnets come in different shapes and sizes.

  7. Types of Magnets • Electro-magnets are temporary magnets that are formed when electricity flows through a coiled wire. • Electromagnets come in all shapes and sizes.

  8. How Magnets are Used Everyday • Magnets are used in many everyday items: • Telephones • Computers and disks • Refrigerators • Maglev Trains • Compasses

  9. Scavenger Hunt • Take the Webquest Challenge. • What is a magnet? • What is magnetism? • What are magnets attracted to? • Explain what a magnetic field is. • Do magnets have poles? Explain • Are there different types of magnets? Name them. • What are magnets made from? • What are some uses of magnets? • Do magnets get weaker? How • Is there any relation between electricity and magnetism? Explain
