Wednesday, June 1st/2011 Magnetism and Electromagnetism III

Today in the beginning of class we had our Electronic Fields booklet handed back to us. Proceeding that we read "Forces on Current In Magnetic Fields" which is from pages 23 to 25, actually before that we had corrected the two electromagnet assignments about the 1st and 2nd Right-Hand Rule that were handed to us on Monday. She later gave us the option to pick up a Grade 11 Physics Review workbooklet. After she then gave us the rest of the period to work on our magnetism lab.

The next scribe will be Gabe.

Monday, May 30th/2011 Magnetism and Electromagnetism

Today in class we have read pages 20-23 on Electromagnetism. We learned that an electric current can create a magnetic force that would be perpendicular to the electric current. We learned that the strength of a magnetic field is proportional to the current when the wire is straight. We learned how to find the direction of the magnetic field on a straight wire, when given the currents direction, by using the first right-hand rule. We also learned how to work with wires that are wrapped in loops (solenoid), by using the second right-hand rule. We were given
electromagnetism assignments to finish and tomorrow we will work on the physics lab worksheet we have, in class!
The next scribe will be Ahmed!

Today in class we got a new booklet called Grade 11 Physics Fields: Magnetism and Electromagnetism. We started off the book with a lab.

The lab was about drawing magnetic field lines using 2 magnets and a compass. Both arrows on the compass are magnetized to point to the North/South Poles on Earth. The 2 magnets both have a North/South end on them, and are opposite in charge. We laid the magnets horizontally from each other, both North ends of the compass facing North, and placed the compass in between them and began moving the compass to see where the arrows point to draw the field lines. Next we flipped one of the magnets so both North ends where facing each other and drew the field lines from there.

When we finished the lab, we had to read and do page 26, which was a study guide.

Sorry this is a day late, I totally forgot about this yesterday.
Not like anyone missed anything anyways since we were all in class, but in case anyone forgot, we went over pages 23 - 28 and got the answers. Then we looked at Millikan's experiment and watched a short clip of that. For homework we had to do pages 29 - 34, but we corrected it today in class.. so this is a pretty pointless scribe.. ANYWAYS

Have a good weekend guys (:

Today we just corrected page 29, 32, and 34 and everyone was here today so i was told not to put the answers up, then after we just studied for the test on tuesday! The test is on the green and ivory booklets and Ms kozoriz said all you need to know is whats in the booklets.

* Make sure you study for the test on TUESDAY MAY 23!
- The test is on the green and ivory booklets.
thats everything have a good long weekend :)

Today we got our new booklet, " Grade 11 Physics Electric Fields" and read pages 1 -10 roughly in class. And we did our first lab for this unit on page 22.
Homework:
Page 23, 24 and 25

May 11, 2011

So on wednesday we first corrected page 39 # 1-7
ANSWERS:
1. a=0.29m/s2
2. m=5kg
3. F=22222N
4. F= 144.56N
5. a=-0.53m/s2
6. w= 666.4N
7. g=9m/s2

Then we read pages 18-22 and did the questions on page 23, 27-28 and 29-30. Sorry it was late, it wouldn't let me post anything. That's everything:)
