The north pole of a strong magnet is dragged down an iron nail from the top to the point 50 times. what will most likely happen when the nail is brought near a pile of small paper clips? the nail will not pick up any paper clips because its domains are not aligned. the nail will not pick up any paper clips because its domains have been aligned. the nail will pick up some paper clips because its domains are not aligned. the nail will pick up some paper clips because its domains have been aligned.

The answer is the fourth option. A magnet will induce the magnetic areas of a nail or paper clip into alignment. The areas in the paper clip are induced into alignment in a means like to the electrical charge polarization in an insulator when an electric object is transported nearby. 

The nail will pick up some paper clips because its domains have been aligned.

Explanation:

Iron is a magnetic element. It is a ferromagnetic element. It is not a permanent magnet but can be magnetized. When the north pole of a strong magnet is dragged down an iron nail from top to the point 50 times, the iron nail would be magnetized and would act as a magnet. This is because the domains would have been aligned. Hence, it would be able to attract some paper clips.

Thus, the correct answer is that the nail will pick up some paper clips because its domains have been aligned.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
