6th grade science magnetism
good luck me
These questions are about science and tje study of magnetism. I wish anyone who is trying this good luck.
the mineral in rocks that is magnetic
What causes an aurora?
Particles from the solar wind penetrate Earths surface
The particles follow earths magnetic field to the magnetic poles.
When particles get close to the surface, they then interact with atoms in the Earths atmosphere.
The interaction causes the atoms to give off glowing lights.
magnetic declination number 1
Streams of electrically charged particles flowing at high speeds from the sun
magnetic declination number 2
the angle between geographic north and north to which a compass needle points
the strong magnetic force between the two neodymium magnets in the base and the top make it float in air
a spinning electron produces a magnetic field that makes the electron behave like a tiny magnet in an atom
made of alloys of platinum and cobalt; and alloys of cobalt and neodymium
any magnet, no matter what it's shape, has two ends each one called a magnetic pole
area of magnetic force around a magnet
a grouping of atoms that have their magnetic fields lined up in the same direction
the region of Earth's magnetic field shaped by solar wind
streams of electrically charged particles flowing at high speeds from the sun
a band of colored lights occasionally appears in the night sky near the magnetic poles
a material that shows strong magnetic effects
every atom has...
a center region and an outer region
center is nucleus
inside the nucleus are protons and neutrons
a tiny, negatively charged particle that usually exists in the outer region of an atom
How can magnets be changed?
cutting them or heating them
How is Earth like a magnet?
like a bar magnet, Earth has a magnetic field surrounding it and two magnetic poles
How is a magnetic field produced in an atom?
How are the domains arranged in material that are magnetized and in ones that are not?
in a magnetized material, the atoms are aligned and all facing one way
a domain that is not magnetized has it's atoms facing every which way
What happens to the domains in iron fling that line up with the magnetic field of a bar magnet?
the filings will line up
What are three properties that magnets have?
magnets attract iron and materials that contain iron
Where is the magnetic effect of a magnet strongest?
at the ends of the poles
one of about 100 basic materials that make up all matter
a positively charged particle found in the nucleus
the attraction or repulsion of magnetic poles
the smallest particle of an element that has all the properties of that element
a magnet made of a material that easily loses its magnetism
magnetic field lines
invisible lines that map out the magnetic field around a magnet
a device with a magnetized needle that can spin freely
Van Allen belts
2 doughnut shaped regions 1,000-25,000 kilometers above Earth that contain electrons and protons traveling at high speeds
any material that attracts iron and materials ttaht contain iron
combined magnetic field
the result of 2 or more two magnetic fields that overlap
a magnet made of a material that keeps its magnetism
magnetic rocks are known as
a particle that does not carry an electrical charge
particles of an atom
the core at the center of every atom
