7. You have been given three beakers with a magnet in each. Pour iron fillings in each one of

third one. Which magnet will attract maximum amount of iron filings? Justify your answer?
PLEASE GIVE WITH JUSTIFICATION
Answers
Answer:
I think 3rd ...
because in 1st beaker fe is present with cold water .it will not react with water but water can influence the attraction
in second beaker fe react with hot water to form ferrous compound so attraction feel by fe is low because it is present in combined form.
so 3rd will feel more attraction because it is present alone.
Answer:
Third one will attract maximum amount of iron fillings.
Explanation:
Because in first one Fe is present with cold water so water will influence the attraction between iron fillings and magnet.
In second one due to presence of hot water it(iron fillings) form ferrous compound so it absolutely affect the attraction because of present in combined form.
In 3rd one magnet is only present with iron fillings so it will attract more iron fillings.
Good luck.
