Question

10. Why do the iron filings (the arc around the magnet) behave in different ways in
the figures given below? (4 marks)
​

Answer 1

Answer:

Each domain may consist of billions of aligned atoms. Under normal conditions, a magnetic material like iron doesn't behave like a magnet because the domains don't have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction.
