2nd Last Scribe of the SEMESTER.

Well, I'm the scribe today and I just got home a few hours ago. Busy busy. We're all getting ready for exam week next week and I'm sure we're all worrying especially for our physics exam. It should be no trouble if preparations are made.

You know what else I'm doing right now? I'm scribing...in 3D. That's right. I have them on. This is an experience. I can see the letters pop out of the screen. Just kidding. But hey. These look awesome compared to those blue and red ones made for that Spy Kids junk. Don't even get me started with Shark Boy/Lava Girl either. Don't you dare.

Before we got to the exam-cram, we corrected 1 - 6 on the worksheet called ELECTROMAGNETISM QUESTIONS. As long as you know your formulas and units, this part of the unit is easy. The main formula here is:

Magnitude of Magnetic Field = Force on wire divided by current in amps(A) x length of wire in meters
( B = FB/Il)

OF COURSE if it's asking for another value, just rearrange the formula and isolate the value the question is seeking. Basically, plug and chug.

ANSWERS [no vectors on the values because I can't do that here.or don't feel like finding the html codes for it]:

1. B = 0.4 T
2. FB = 2.3 N
3. B = 0.2 T
4. FB = 1.6 N
5. B = 0.13 T
6. B = 0.15 T

As for the rest of those questions on that sheet, we didn't go over them because we basically did another worksheet with similar questions.

Click here if you really want them again. Or for Matthew's abridged vers. here.

Then we went on with exam review which I think helps a lot. I've been doing some reading over the past units as well. Sure I'm not completely finished the review but I've done something. Even started typing out shorter notes and highlighting. So I think I'll be good.

I'm sure we'll probably go over some answers in the review tomorrow, right before the exam on Monday!

Hmmm. what else happened? I guess, people went on to their own little worlds after studying a bit. All I remember was having a conversation with Matthew and Ann about Home Alone and past experiences in the Eatons building before it became the MTS Centre. I really want tickets to SYTYCD Canada.. arghhh

Thinking of Eatons makes Matthew think of that soap opera The Young and the Restless and for me, well it makes me think of the time when I was stabbed in the eye by a kid with a plastic knife. It's quite funny looking back on it now, but I still have somewhat of a scar. LOL. I just usually say I got the scar from being in a war or something. Oh well . I'm going into tangents right now... so yeah. But hey.. what does EATONS remind you of?

I guess I'll get back to studying more physics and calculus. I'm pretty sure I'll do well on this exam and hopefully raise my mark. I don't understand though why I'm still getting this mark. I mean sure, I've had one or two bad tests but they weren't that bad. And I have handed in all my sheets. I'm sorry I'm being annoying, but this is bugging me. I just need a little justification here. I guess I'm just a persistent little bugger. I guess I'll worry about that tomorrow.

Now now.. since I wasn't the LAST LAST scribe, which I thought I was until I realized it was only THURSDAY, I shall pass on my scribing powers. To who.......????? uhh.... okay...WONDERBREAD, who has great announcing abilities.. I think it is you Daniel..right?

MAY THE FORCES OF PHYSICS BE WITH YOU.

PS...It would be cool if we had like... a PARTEH tmro.. like maybe a potluck thing or just a plain.. bring food thing. **cough I'm emphasizing FOOD **

Uhmmmmm Finally It's Me!!! XD

Hahaha hmmm hello fellow classmates ! Prepare for the most mind shattering blog post of your entire life.

Today in physics we did a quick review of the right hand rule in regards to magnetic fields.

First Right Hand Rule: Tells us direction of flow and what the magnetic field looks like around a wire with a current.

Second Rule: Tells us polarity and flow of electrical current in an electromagnet.

Third Rule: Tells us direction of current, polarity, and the force being exerted by a wire with a current flowing through it placed in a magnetic field.


We also quickly reviewed our new formula B= FB/IL

B is the magnitude of the magnetic field. This is measured in teslas, or N/A-m (newtons/ ampere-meter)

FB represents the force of the magnetic field

I represents the current, measured in amperes or amps.

L represents the length of the wire/conductor in meters.

Sooooo that's that part out of the way. As far as work goes, today we focused on a sheet called Electromagnetism Questions (original title, no?)

For the first 6, we simply use the formula B= FB/IL, although on occasion we had to derive the equation to solve for force, i.e. FB = BIL. These are actually fairly simple and I think it's probably more useful to you if you practice these ones on your own to get the answers rather than having me post 'em here.

Questions 7-13 are basically reviews and carbon copies of questions we have done on other sheets, so I also will not delve too deeply into those.

14 is somewhat of a less touched upon area. Magnetic declination refers to the angle between the local magnetic field (direction compass points north) and what is considered "true north".

15 is fairly straightforward. Both a stationary and moving charge have electric fields due to charge, and gravitational fields due to mass. A moving charge, however will also have a magnetic field. Yeah.. i think that's it? haha...

16. The magnetic domains in the iron will align with the external magnetic field, adding to the overall strength of the field. Woohoo... XD

17.Maximum magnetic force will be experienced when a charged particle travels perpendicular to the magnetic field. Minimum force will be experienced when the charged particle travels parallel.

yeah guess that's it lol. If we finished that sheet, we got to work on exam reviews basically, and with the exam approaching fast its best to learn your stuff now rather than waiting until the last minute (like I should talk..).

Hmmm one more thing XD i hereby declare .:. J + ME .:. aka Jamie to be the next scribe. Lol, that is all my good people... Happy Physics-ing XD
