What three minerals are attracted to a magnet?
CHECK ALL THAT APPLY.
nickel
silver
cobalt
aluminum
copper
iron
gold
What is it about these minerals that make the Earth one big magnet?
Because gravity pulls us to the Earth, that's how we know the Earth is a magnet.
Earth is filled with minerals that make it like a magnet.
Earth is not like a magnet at all.
Earth is like the magnets you put on your refrigerator.
Magnetism is made up of moving electrons. Where do these moving electrons come from when making an electromagnet?
a battery
a coil
a weight
none of the above
What is it that makes a magnet different from a piece of iron that is not magnetic?
The electrons in iron are spinning in all different directions, and the electrons in a magnet are spinning in all different directions.
The electrons in iron are spinning in all different directions, while the electrons in a magnet are lined up in the same direction.
The electrons in iron are lined up in the same direction, and the electrons in a magnet are lined up in the same direction.
What makes magnetic objects different from non-magnetic objects?
Magnetic force flows from the north to the sides.
Electrons spin in different, random directions.
Electrons are all aligned in the same direction.
Magnetic force flows from the south to the sides.
Just like the N and S poles on bar magnets, electrons and protons _______ each other.
push apart
attract
repel
repulse
When an electric current flows through a wire, a magnetic field is created. To increase the power of the magnetic field, _______ .

What do you think the blue circles going around the wire represent?
protons
neutrons
electrons
nothing
Put the items into the TRUE or FALSE category.
Iron, nickel, and cobalt can all be made to be magnetic
Opposite poles of magnets attract, and similar poles repel each other.
Magnets are found naturally in the Earth.
The north poles of two different magnets will attract each other.
Most magnets are made from 100% aluminum
Increasing the number of coils in an electromagnet will increase the power of the magnet.
