Question

A bar magnet is immersed in a heap of iron filings and pulled out. The amount of iron filings clung to ______.

• A. the north pole is almost equal to the south pole
• B. the north pole is greater than to the south pole
• C. the north pole is lesser than to the south pole
• D. the magnet will be the same throughout the length of the bar magnet

Answer 1

The correct option is A the north pole is almost equal to the south pole

Since, the magnetic strength of both the poles are the same, hence, the amount of iron filings clung to both the poles are equal. Also, the amount of iron filings clung is not uniform across the bar magnet.
