# Worksheet: Magnets and Force

In this worksheet, we will practice describing the effects of magnetic interactions between two objects that are not in contact.

Q4:

Emma tested three different magnets to see which could hold the most paper clips.

The results are shown in the table.

Magnet A Magnet B Magnet C
12 8 4

Which magnet is the strongest?

• AMagnet B
• BMagnet C
• CMagnet A

Q5:

True or False: The further apart two magnets are from one another, the stronger the forces that attract or repel the magnets.

• ATrue
• BFalse

Q6:

• ARepel
• BAttract

Q7:

Fill in the blank: As two magnets move further away from each other, the strength of attraction .

• Abecomes weaker
• Bbecomes stronger
• Cstays the same

Q8:

Choose the statement that correctly describes the diagram.

• AThe magnet is repelling the paper clip.
• BThe magnet is attracting the paper clip.

Q11:

Magnets sometimes have the letters N and S painted on either end.

What is the name given to the ends of a magnet?

• APoles
• BFields
• CPoints

Q12:

Choose the statement that describes what would happen to the magnets shown in the diagram.

• AThe magnets would be attracted to each other.
• BThe magnets would repel each other.
• CThe forces are equal; the magnets would not move.
