Hi everyone:
Good luck to you in writing the exam. Hope this blog helped you in the course.
Thanks to all who contributed, in a big way or in a small way.
See you in grade 12 physics.

Magnetic Fields
By Awot
Hello classmates!
Today Ms.k and us corrected the Questions from yesterday on the text book. It was on page 510. Ms.k has uploaded the corrections on the blog by the way. After that, Ms.k drew a diagram and explained the difference between conventional current flow of positive charges and electron flow theory. On conventional current she showed us how to determine the direction of the current and North using our fingers.
For monday we were given three sheets of assignments. They are Electromagnetism assignments on conventional current. One of them is a page back to back and the other two are just on page each. Thats all we did today and that is all we have to do for monday.
As Ms.k said there is only a couple of days left. Lets not wait until the day before the exam and panic.

Just Another Scribe
Yes, it's me the one and only... doing a late post, nothing new. ONLY 11 DAYS UNTIL EXAM guys. Today we officially started our unit on Magnetic Fields; we started off the class with introduction notes which are in the slide posted preview to the last slide before mine, haha hope everyone got that. Then, we were assigned to read pages 492 – 496 in the physics textbook and answer 10 questions which I’m positive no one finished, including me. But, here are the first six questions frome th Reviwing Concepts section on page 510 of the text book:
1. Magnetic attraction only occurs between a North and South Pole. Magnetic repulsion occurs between 2 North poles or 2 South poles.
2. A permanent magnet doesn’t lose its magnetism easily. A temporary magnet is only a magnet when it is under the influence /or attracted to a permanent magnet.
3. 3 most common magnetic elements: (alnico)
-Aluminum
-Nickel
-Cobalt

6. A broken magnet cannot have isolated poles because they always come in pairs.
And that will be in for my last scribe of grade 11 Physics
