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 ?
The answers to the questions are as follows:
(a) The iron fillings arrange themselves in a pattern because they get attracted by the bar magnet. The pattern that they form can also be called the magnetic field lines of the bar magnet.
(b)The crowding of the iron fillings represent that the power of the magnetic field is highest at the ends of the bar magnet.
(c)The lines along which the iron fillings align represents the magnetic field lines.
