Maria works in a hardware store. a bin of aluminum nails and a bin of iron nails are knocked over, and the nails get mixed up. both sets of nails are the same color and size.

what makes separating the nails a fairly easy job?

a) aluminum is heavier and iron is lighter.
b) iron settles in water, while aluminum floats.
c) aluminum is magnetic, and iron is non-magnetic.
d) iron is magnetic, and aluminum is non-magnetic

Option (D) is the correct answer.

Explanation:

Iron gets attracted by magnet as magnet provides a magnetic field to the iron. As a result, iron gets attracted towards the magnet.

Whereas magnet does not provide any magnetic field to the iron. Hence, aluminium does not get attracted by a magnet.

Therefore, we can conclude that iron is magnetic, and aluminum is non-magnetic makes separating the nails a fairly easy job.
