True or False: The geographic north pole is actually the north pole of a magnet

• True

• False

Answer explanation

The geographic north pole refers to the northernmost point on Earth. There is a magnet field around the Earth, but the geographic north pole more closely aligns with the magnetic south pole.

What do opposite poles of a magnet do?

• Attract

• Repel

Answer explanation

Opposite poles of a magnet, such as north and south, attract each other. This fundamental property of magnets is why the correct answer is 'Attract'.

What do like or same poles of a magnet do?

• Attract

• Repel

Answer explanation

Like poles of a magnet, such as two north poles or two south poles, repel each other. This is a fundamental property of magnets, where opposite poles attract and like poles repel.

What pole of a magnet does a compass point to?

• North

• South

Answer explanation

A compass points to the magnetic south pole of the Earth, which is actually the geographic north pole. Therefore, the correct answer is South, as the compass needle is attracted to the magnetic south.

What do we call the area around a magnet that the magnet affects?

• Force Field

• Magnetic Force

• Magnetic Field

• Attraction Zone

Answer explanation

The area around a magnet that it affects is called the 'Magnetic Field'. This field represents the influence of the magnet on other magnetic materials and charged particles, distinguishing it from terms like 'Force Field' or 'Attraction Zone'.

What do we call things that are attracted to a magnet, but are NOT magnets?

• Magnets

• Magnetic

• Ferromagnetic

• Magnetized

Answer explanation

Things that are attracted to a magnet but are not magnets themselves are called ferromagnetic materials. These materials can become magnetized in the presence of a magnetic field but do not have their own magnetic field.

What kind of metal is ferromagnetic?

• Iron

• Aluminum

• Steel

• Tin

Answer explanation

Iron is a classic example of a ferromagnetic metal, meaning it can be magnetized and attracted to magnets. Aluminum, steel, and tin do not exhibit ferromagnetism in the same way that iron does.

What is a temporary magnet?

• A magnet that has always been a magnet

• A ferromagnetic material

• A magnet that gets its poles reversed

• A magnet that can be turned off and on

Answer explanation

A temporary magnet is one that can be turned off and on, unlike permanent magnets that retain their magnetism. This characteristic allows temporary magnets to be used in various applications where magnetism is needed only intermittently.

Are magnets a contact force?

• Yes

• No

Answer explanation

No, magnets are not a contact force because they can exert forces at a distance without direct contact. They create magnetic fields that influence other magnetic materials or charged particles nearby.

Does magnetism need a medium, like air?

• Yes

• No

Answer explanation

Magnetism does not require a medium like air to propagate. It can occur in a vacuum and can exist independently of any material medium.
