Which of the following statements are true? Check all that apply. A. Earth's geographic south pole is also a magnetic south pole. B. Scientists have evidence that single isolated magnetic poles, called magnetic monopoles, exist. C. The north pole of a bar magnet will attract the south pole of another bar magnet. D. The south poles of two bar magnets will repel each other. E. The north poles of two bar magnets will attract each other. F. Earth's geographic north pole is actually a magnetic south pole.

C.The north pole of a bar magnet will attract the south pole of another bar magnet.

D.The south poles of two bar magnets will repel each other.

F.Earth's geographic north pole is actually a magnetic south pole.

Explanation:

The magnetic field is a region of space that exerts a force on charged particles in motion or on magnets.

A magnet is an object that produces a magnetic field in the region around it - a magnet always consists of a north pole and of a south pole; it is not possible to create a magnetic monopole: if a magnet is cut in a half, we end up with two new magnets, each of them having its own north and south pole.

The lines showing the direction of the magnetic field always go from the north pole towards the south pole.

When a magnet is placed near another magnet, the two magnets can attract/repel each other. In particular:

- Same poles (north-north and south-south) repel each other

- Opposite poles (north-south) attract each other

Moreover, the Earth has also a magnetic field, and its axis acts as a huge magnet. The location of the magnetic North pole corresponds to the location of the geographic South pole, and vice-versa.

According to what we said so far, the correct statements are:

C.The north pole of a bar magnet will attract the south pole of another bar magnet.

D.The south poles of two bar magnets will repel each other.

F.Earth's geographic north pole is actually a magnetic south pole.
