A student fixes a white sheet of paper on a drawing board. He places a bar magnet in the centre and sprinkles some iron filings uniformly around the bar magnet. Then he taps gently and observes that iron filings arrange themselves in a certain pattern.
- Why do iron filings arrange themselves in a particular pattern?
- Which physical quantity is indicated by the pattern of field lines around the bar magnet?
- State any two properties of magnetic field lines.
Name the poles P, Q, Rand S of the magnets in the following figures 'a' and 'b':

Assertion (A): Magnetic field lines never intersect each other.
Reason (R): If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
