  1. FYI Vocabulary Quiz- Friday No after school tutorials…THURS or FRI (sorry!)

  2. Vocabulary Review-Magnetism

  3. Magnetic domain • A microscopic cluster of atoms with their magnetic fields aligned

  4. Faraday’s Law • Induced voltage in a coil is proportional to the product of the number of loops and the rate at which the magnetic field changes within those loops

  5. Magnetic Field • A force field that fills the space around every magnet or current carrying wire

  6. Electromagnetic Induction • The phenomenon of inducing a voltage in a conductor by changing the magnetic field near the conductor

  7. How can you ruin a magnet? Drop it Heat it Store it improperly

  8. Magnetic Poles

  9. If you suspend a bar magnet from its center it will act as a c________

  10. North and South Poles- all magnets have them • The end that points north (means north seeking) and is called the north pole • The end that points south (means south seeking) is called the south pole

  11. Does it make sense that the northpole of a magnet can be attracted to the north pole of the earth?

  12. A north magnetic pole never exists without a south pole =

  13. Magnetic Fields

  14. The space around a magnet is where the magnetic force is exerted • The field lines are always drawn from N______ to S_________ • North to South

  15. Draw the magnetic lines of force around the bar magnet

  16. How can you determine where the strength on a magnet is stronger? • The lines will be closer together where they are stronger
