Answer» i) I observe that the uniformly spread iron filings come close and get concentrate at two points of the paper sheet. At some distance, I found some scattered iron filings between these two points. ii) No. the ends of the bar magnet attract more iron filings than the middle part of the magnet. iii) Yes, uniformly spread iron filings changed their pattern and concentrated more at endpoints of the bar magnet. Scattered iron filings between these two points are somehow in some lines from one point to other. |
