Answer 1

Answer:

c, d, and f.

Explanation:

Let us look at each of the statements one at a time:

a. Earth's geographic south pole is also a magnetic south pole.

This is not true. Earths magnetic south pole is slightly off (2,860 km away) from earth's geographical south pole.

b. Scientists have evidence that single isolated magnetic poles, called magnetic monopoles, exist.

Nope. So far no evidence yet exists that hypothetical magnetic monopoles exist.

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

True, since opposite ends of a magnet attract and like ends repel.

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

Also true since like poles of a magnetic repel each other.

e. The north poles of two bar magnets will attract each other.

No, the north poles of two magnets will repel each other since they have the same polarity.

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

Yes. If you call the point of the needle that points north the north pole of the compass, then it points north because it is attracted to the south pole of earth's magnetic field. (like repel opposites attract)
