Salaam...yerterday, we were having an experiment which was then divided into three subsets. The class was split into four groups. Below are several photos that describe how magnetic field effects iron fillings. I will explain it under the photo in caption.
I am sad, because there was one more experiment, of which I did not manage to take picture. It was the effect of number of turns towards magnetic field strength, B. *So sad..* nevermind.. hey, Sven! Stop jinxing..
