okay this is an old picture and i already used it but i saw that it contained an electromagnet in it...the power lines which i think are dead...but anyways yah the power lines that you see everyday while driving or just observing are electromagnets because they have current running through them...and are conducting wires so yah needs electricity to be a magnet therefore it is an electromagnet...
also while i was at blockbuster this weekend renting a scary movie:) umm i had to swipe my blockbuster card and then my credit card...when i did i noticed the screen was facing me so i could see everything that the computer read from my card and i remembered mr. Kohara telling me that that was the work of little magnets on my card..i looked closely as the computer read my full name, address, credit card #, date i became a member of blockbuster and all that jazz...its CRAZY how magnets can do that and how humans came up with that stuff...even that video in class about the hard drive blew my mind...i made my own computer last year and when i was deciding on which harddrive to use i didn't really know what all the numbers and stuff meant...i jus chose the one with the biggest numbers:P but now i can see and know how a hard drive works...and i was jus amazed that a human like me made that!!!
