they will attract each other
they will repel each other
both magnets will turn to the left
both magnets will turn to the right
Where is the force of attraction the strongest on a magnet?
at the poles
in the middle
above the magnet
below the magnet
This substance is...
magnetized
unmagnetized
positively charged
negatively charged
You know this substance is magnetized because...
the domains point to the right
the arrows are drawn in red and green
the domains are aligned
the domains are random
In this image, the pattern of iron filings shows the ____________________________.
north pole
south pole
magnetic field
bar magnet
A stronger magnetic field is found where...
the field lines are longer
the field lines are shorter
the field lines are closer together
the field lines are father apart
Where is the magnetic force the strongest in this picture?
location 1
location 2
location 3
location 4
A permanent magnet...
has no magnetic domains until a magnet is near
has magnetic domains aligned only when another magnet is near
has magnetic domain aligned all the time
has no magnetic domains
What happens when two south poles of a magnet are placed together?
they repel
they attract
they cancel each other out
the strength of the magnet is doubled
Are the magnetic field lines in this picture correct?
yes, because the north pole is on the left in all the pictures
yes, because they point from the north pole to the south pole
no, because they point from the north pole to the south pole
no, because the north pole should be on the right in all pictures
The area of magnetic force around a magnet is known as its __________________________.
magnetic tan lines
magnetic fan lines
mangetic declination
magnetic field
Dylan puts two magnetic toy trains very close to each other on a track. What will happen next and why?
the trains will not move because the magnets are not touching
the trains will move closer to each other because the magnetic force will pull the trains together
the trains will move away from each other because the magnetic force will push the trains apart
the trains will move away from each other because the magnets are not touching
Why are paper clips attracted to magnets?
paper clips contain silver
paper clips contain aluminum
paper clips contain iron
paper clips contain tin
Which of the following is true of a bar magnet?
its magnetic field is strongest near its center
it is surrounded by a magnetic field
the north pole is stronger than the south pole
the south pole is stronger than the north pole
The system of magnets in the image are ________________________________ each other.
attracting

neutralizing
Where is Earth's magnetic field strongest?
near the magnetic poles
closest to the equator
near the geographic poles
it's the same strength at all locations
As magnets get farther apart, the strength of the field becomes...
stronger
weaker
stays the same
What would happen if you cut a bar magnet in half?
both pieces would lose its magnetic field
both pieces would have its own north and south pole
one piece would be only a north pole and the other would only be a south pole
one would still be a magnet, the other would no longer be magnetic
