Question

You have been given three beakers with a magnet in each. Pour iron filings in each one of them and then pour very cold water in one, very hot water in the second, and no water in the third one. Which magnet will attract the maximum amount of iron filings? Justify your answer.

A) The magnet in cold water, as cold temperatures increase magnetic attraction.
B) The magnet in hot water, as hot temperatures increase magnetic attraction.
C) The magnet in the beaker with no water, as water has no effect on magnetic attraction.
D) The magnets in all three beakers will attract the same amount of iron filings.

Answer 1

The magnet in the beaker with no water will attract the maximum amount of iron filings as water has no effect on magnetic attraction.

Step-by-step explanation:

The magnet in the beaker with no water will attract the maximum amount of iron filings. Water has no effect on magnetic attraction. The presence of water does not alter the magnetic properties of the magnet or the iron filings. Therefore, the magnet in the beaker with no water will have the same magnetic attraction as the magnets in the beakers with cold and hot water.
