What happens when the small bar magnet kept on the glass and iron filings sprinkled on glass ?
What happens when the small bar magnet kept on the glass and iron filings sprinkled on glass ?
When iron filings sprinkled, the arrangement of iron filing is as below :
The pattern suggests that :
$(i)$ The patterns of the iron filings suggests that the magnet has two poles similar to the positive and negative charge of an electric dipole.
- One pole is designated the north pole and the other the south pole.
$(ii)$ When suspended freely, these poles point towards the geographic north and south poles respectively.
$(iii)$ A similar pattern of iron filings is observed around a current carrying solenoid.
