What is the magnetic attraction or repulsion of a magnet called?
the magnetic domain
the magnetic field
the magnetic pole
the magnetic force
Which type of magnet does not lose it's magnetic properties easily.
a permanent magnet
an electromagnet
a temporary magnet
a nail rubbed across the north pole of a magnet
The space in which the magnetic effects exists is called

the magnetic equator
the magnetic material
Paper clips and staples are attracted to magnets because paper clips and staples are
permanent magnets
temporary magnets
magnetic materials
magnetic domains
What are the two magnetic forces?
attraction
equilibrium
magnetic acceleration
repulsion
Are the magnetic field lines in the picture correct?
Yes, because they point from north to south.
No, because they point from north to south (they're supposed to go the other way).
Yes, because the North pole is on the left in all pictures.
No, because the North pole is on the left in all pictures (it's supposed to be on the right).
Looking at the field lines in this picture, these two magnets are ________
Attracting
Repelling
Attracting and Repelling
Doing nothing
What is the shape of a magnetic field around the Earth?
What is the shape of a magnetic field around a wire?
A ________ is a device that has a magnet on a needle that spins freely. It is used for navigation because its needle usually points north.
calculator
ruler
compass
map
Select the diagram with the weakest magnetic field
Where is the magnetic field the strongest around a bar magnet?
far away from the magnet
at the side of the magnet
at the poles
above the magnet
Why does a compass needle point north?
The compass is a bar magnet
Because north is up and you know that up is always north or the stratosphere.
Because it's magic
Because the North end of the compass lines up with the Earth's magnetic south pole
The area of magnetic force around a magnet is known as its _____________.
magnetic field
magnetic declination
magnetic fan lines
magnetic tan lines
To pull objects toward each other
Attract
Repell
Convert
Energy
As the magnets get farther apart, the strength of the fields get.....
Weaker
Stronger
Stay the same
Which statement is true about both magnetic and electric fields?
Like charges repel each other
Like charges attract each other
Like poles attract each other
A clumsy student drops a bar magnet and it breaks into this configuration. Afterwards, what is the result for the left and right magnets respectively?
N-N on the left and S-S on the right
N-S on the left and N-S on the right
S-N on the left and S-N on the right
S-S on the left and N-N on the right
A magnet has a _______ pole and a _______ pole.
north, south
east, west
positive, negative
red, blue
Which of the following would a magnet ATTRACT?
A copper penny
An iron nail
A piece of glass
A wood block
All metals are magnetic.
True
False
What is a difference between a magnet and a magnetic material?
Magnets are metals and magnetic materials are not.
Magnetic materials attract to either pole of a magnet; magnets only attract to opposite poles.
Magnets are attracted to magnets and magnetic materials are repelled by magnets.
Magnets and magnetic materials are the same thing.
Why does the Earth have a magnetic field?
Because of all the magnets on the Earth's surface
Because the Earth is a magnet
Because the Earth is made of copper
Because Earth is orbiting around the sun

In order to create these magnetic fields, what would the pole order have to be on the covered magnet?
SN
NS
It could be either order.
It is not a magnet - it has no poles.
What does this picture represent?
