... the experiment, and also exactly how far the electromagnet should be away from the iron bar. "h I did a preliminary experiment before the actual experiment "h I tested what was a safe current. I found out that a current up to six amps was satisfactory. We also tested what was a safe distance for an electromagnet from the iron bar-ten centimeters was too far, two centimeters was too close, five centimeters was a satisfactory distance. Analysing Evidence & Drawing conclusions To draw a conclusion from my graph, first of all I would divide it into three sections: Section A (the bottom), section B (the middle) and section C (the top). This would now make it easier to describe. The first section (A) looks like it does because for the amount of current put in, only a few of the domains had lined up. My second reading that I took was inaccurate, so on my graph I have ...
