Question

magnets have two different ends, or magnetic poles—a north pole and a south pole. both poles of a magnet always attract a magnetic material. but two magnets can attract or repel each other depending on how their magnetic poles are oriented.
when two like poles (two north poles or two south poles) are near each other, the magnetic force between the magnets causes them to repel.
when two opposite poles are near each other, the magnetic force between the magnets causes them to attract.
select the true statements.
all magnets have two magnetic poles.
a south pole attracts a north pole of another magnet.
a magnet can repel a magnetic material.
two like poles repel each other.

Explanation:

1. "All magnets have two magnetic poles" - The text states "Magnets have two different ends, or magnetic poles", so this is true.
2. "A south pole attracts a north pole of another magnet" - The text says "When two opposite poles are near each other, the magnetic force between the magnets causes them to attract", and south and north are opposite poles, so this is true.
3. "A magnet can repel a magnetic material" - The text says "Both poles of a magnet always attract a magnetic material", so this is false (the original check here is incorrect as per the text).
4. "Two like poles repel each other" - The text states "When two like poles (two north poles or two south poles) are near each other, the magnetic force between the magnets causes them to repel", so this is true.

Correct true statements:

• All magnets have two magnetic poles.
• A south pole attracts a north pole of another magnet.
• Two like poles repel each other.

(Note: The third statement "A magnet can repel a magnetic material" is false as per the given text which says magnets always attract magnetic materials.)

Answer:

• All magnets have two magnetic poles.
• A south pole attracts a north pole of another magnet.
• Two like poles repel each other.
