Magnetism Quiz

Which of the following materials is one of the most anti-ferromagnetic materials?

• Cobalt

• Chromium

• Nickel

• Iron

What is the reason why chromium, despite being a very magnetic atom, is a very un-magnetic solid?

• It has no protons

• Its electrons cancel out each other's magnetic fields

• It has no electrons

• It has no nucleus

What is the reason why there are only a limited number of suitable materials for building a magnet?

• It is difficult to find the right shape

• It is difficult to generate a magnetic field

• It is difficult to fulfill the criteria for magnetism

• It is difficult to align the magnetic domains

What can you do to generate a magnetic field in any electrical conductor?

• Apply pressure

• Expose it to light

• Run a current through it

• Heat it up

What is the main reason why atoms in the middle of the periodic table are magnetic?

• They have no electrons

• They have no nucleus

• They have no protons

• They have full outer electron shells

What is the name of the property that particles with electric charge have, making them tiny magnets?

• Tiny magnet

• Electric field

• Gravitational pull

• Intrinsic magnetic moment

Which of the following materials is one of the most anti-ferromagnetic materials?

• Cobalt

If you place the North pole of a magnet next to the South pole of another magnet, they will:

• Attract

• Repel

• Do nothing

• Shatter

On Earth, where is Magnetic North approximately located?

• The Equator
• The North Pole
• The South Pole
• New Brighton

As the distance between two magnets increases (they get farther apart), the force between them:

• Increases
• Decreases
• Stays the Same
