What happens when the north pole of one magnet is brought close to the south pole of another magnet?

• They repel each other.

• They attract each other.

• Nothing happens.

• They demagnetize each other.

Answer explanation

When the north pole of one magnet is brought close to the south pole of another magnet, they attract each other due to the magnetic forces between opposite poles.

Process by which a non-magnetic material becomes a magnet temporarily is called

(a)  

How can I make a permanent magnet no longer magnetic? (Select all that apply)

• Hit/Drop it repeatedly

• Put it near a tv or cell phone

• Submerge it in water for several hours

• Put it next to another magnet long term

• Heat it up

Answer explanation

To make a permanent magnet no longer magnetic, you can hit/drop it repeatedly and heat it up. These actions disrupt the alignment of magnetic domains, reducing the magnetism.

A paper clip is an example of a:

• magnetic material

• permanent magnet

• bar magnet

• insulator

Answer explanation

A paper clip is an example of a magnetic material because it can be attracted to magnets due to its magnetic properties.

In un-magnetized materials the domains are __________ aligned.

• super

• slightly

• randomly

• always

Answer explanation

In un-magnetized materials, the domains are randomly aligned, meaning they have no specific orientation or arrangement.

Magnets that are arranged like this will _______. 

• move away from each other (repel)

• move towards each other (attract)

Answer explanation

Magnets arranged like this will move towards each other (attract) due to opposite poles facing each other, creating a magnetic attraction.

True or False: All metals stick to magnets.

• True

• False

Answer explanation

Not all metals stick to magnets, so the statement is False. Only ferromagnetic metals like iron, nickel, and cobalt are attracted to magnets.

Which of the following is NOT naturally magnetic?

• iron

• copper

• nickel
