Which model below correctly represents an object with a correct pair of magnetic domains?

The term magnetism comes from the region of Magnesia, a city in Western Turkey, where Greeks found lodestones, which attracted iron pieces across the space.   It is also observed that, magnets attract as well as repel.  We can explain this dual nature of magnetic force by proposing that each magnet has two poles, north pole (N) and south pole (S).  You will observe two things during the activities:

1)      When two magnets are brought near each other, like poles repel; opposite poles attract.

2)      When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.

hope this helps u stay safe
