Question

a student fixes a sheet of white paper on a drawing board he places a bar magnet in the center of it he sprinkles some iron fillings uniformly around the bar magnet then the taps the boards gently and observes that the iron fillings arrange themselves in a particular pattern
(a) why do iron fillings arrange in a pattern?
(b) what does the crowding of iron fillings at the end of the magnet indicate
(c) what does the lines along which the iron fillings 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

Answer 1

Answer:

a iron fillings attract in a particular pattern because each particle are attracted to either of the two poles of magnet due to which some attract each other while other deflect each other so a symetric geometrical pattern is formed
