Yesterday, we watched 'same same' guy, got our physics test back, worked on questions 1-10 in the textbook and got 2 worksheets which we corrected today! wheeeeeeeeeeeeeeeeeeee~!
CORRECTIONS (cuz that's all that we did today)

2.Difference is that electic charges can be seperated but magnetic poles are always in pairs.
3. A magntic field is the region of space around a magnet. Its source is the domain (which contains spinning electrons)
4. A domin consists of a bunch of spinning electrons oriented in the same direction.
5. Heating or dropping a magnet will disturb the domains and it will mix up and pont in different directions.
6. north
7. geographic north pole OR magetic south pole
8. domains
9. b. tin

11. a. north
12. Use a compass or bar magnet to se if it attracts/ repel.
13.
