Magnetic Fields

hi everyone!!! it's me, LORENZ!!! i guess this will be my last post for our class. Yesterday, we had a sub and she gave us a booklet 2.3 Ferromagnetism and the Domain Theory of Magnetism. She gave us time to read through it and then she told us to answer those 4 questions on 2.9 Exercise located at the back of the last page. Here are the answers that i got:

1) When magnetizing a steel nail, you must stroke it against a permanent magnet and heat or drop the magnet to lose the magnetization.

2) No, because aluminum can't be magnetize, must be made of a ferromagnetic material.

3) Real magnet can be repelled or attracted to either end, and ferromagnetic can stick on both ends.

4) It will not reflect solar radar from the sun.

After we finish correcting those 4 questions, she gave us some notes about Right Hand Rule. I am sorry but i did not copy those notes because it is already in our Chapter 24 Study Guide but i hope that everyone is now preparing for our upcoming final exam on Monday, January 26, 2009 in the school Gym at 1pm.

Like what nelsa said, everyone is been trying to finish their blog so i hope that everyone will get to finish theirs. So to continue this, i choose Lynel Pobre to do the next blog since she didn't get to do hers last time because of her other homework.

I'll see you guys on Monday!!=)
