A student fixes a sheet of white paper on a drawing board. He places a bar magnet in the centre of it. He sprinkles some iron filings uniformly around the bar magnet. Then he taps the board gently and observes that the iron filings arrange themselves in a particular pattern. (a) Why do iron filings arrange in a pattern? (b) What does the crowding of iron filings at the end of the magnet indicate ? (c) What does the lines, along which the iron filings align, represent? (d) Draw a neat diagram to show the magnetic field lines around a bar magnet. (e) Write any two properties of magnetic field lines.
