A student fixes a sheet of white paper on 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 the iron filings arrange in a pattern? b)What does the crowding of iron filings at the end of the magnet indicates ? c) What does the lines along which the iron filings align represent ?
Answers
Please find below the answers to the questions:
a) Due to the force exerted by the magnet within its magnetic field the iron fillings get attracted and arrange themselves in a particular pattern which is given by the magnetic lines of bar magnet.
b)Crowding of iron filings at the ends of the magnet indicates that the magnetic field is strongest near the poles of the magnet.
c)The lines along which the iron fillings arrange themselves represent magnetic field lines of the bar magnet.
a) The iron fillings get arranged in a particular pattern. This is due to the force that the bar magnet exerts on the iron fillings.
b) The crowding pattern of the iron fillings at the end of the magnet indicate the magnetic lines that are formed when the iron fillings are arranged.
c) The crowding of the iron fillings and the lines indicate the strong magnetic field formation, and the strength of the magnetic field is indicated by the closeness of the field lines.
