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 north pole 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
