Hovercars
We’ve learned from our research the basic properties of magnetism.
Magnetism, of course, is a force that, by its electricity, attracts all objects
in its magnetic field. What we proposed to do is to create an electromagnet,
enhanced with electrical energy.Of course, the dream of hovercars has already
been invented, and most probably the only reason we are not using them is for
the sake of simplicity and easiness, as opposed to some of the complications of
magnet travel. However, even some are commonly used (in comparison with the
others) today, that are an exception to the previous sentence. The MagLev
(short for magnetic levitation) train was invented by the German Alfred Zehden,
who patented it in the United States.
What we propose doing is similar to his idea. Although we haven’t
worked out all the details specifically, the big idea is to create a car with
matching poles in relation to the floor below. This will make them repel
against each other, and thus making the vehicle hover. The magnetic field of the
car and the floor are large, but small enough to make sure that they do not
crash into other building. How the floor will be magnetised is still to be
considered, however we all agree that there has to be some sort of rebuilding
of the streets for magnetic cars. And whiile this happens, we have an idea for
how to use the cars. Instead of the whole road being magnetised, we only need a
platform, of the same pole as the magnets of the car, that moves around under
the car, and helps it move. Of course, this should only be temporal until the
roads are paved with magnetic material, but it could help popularize the cars
while there are no resources to drive it.

WHAT I LEARNED
(Simple English Wikipedia)
1.
Magnetism is a term used in physics describing
a force that attracts and repels objects. Magnetism can be made by things we
call magnets, or can also be made by electricity in a wire (called an
electromagnet). Magnetic attraction is when magnets are put near to magnetic
objects, the magnet will attract the magnetic object and pull it towards the
magnet until it is as near as it can get or touching it. Magnets can also repel
other magnets. Most objects that are attracted to magnets have iron in them.
Most other metals, such as aluminum, are not attracted to magnets. Magnetism is
a property that can be naturally found in such materials as iron, but can also
be caused by electricity being conducted through a non-magnetic material. This
is called an electromagnet. If a magnet of one pole is put near a magnetic
field of the opposite pole, both can attract each other and move as close as
possible towards each other. Or, if they are both of the same pole, they will
repel each other, and cause a force that attempts to distance themselves from
each other. One end of a magnet is of
the North Pole, and the other is of the South Pole. The north pole magnet, if held freely, will
always point to the geographical north. This property is the basis of
compasses.

What is a magnetic field?
A
field fills the space between matter, and how much force this matter can have
on other matter. Several different types of fields exist. Gravity and electric
are two. Another is the magnetic field. A magnetic field only comes into play
when electric charges are moving. It is
a field because a magnetic field determines how much force an electric charge
will exert on another current.
What is a permanent magnet?
Mostly
everything is non-magnetic. The difference is when the motion of an electron
generates a magnetic field cancelled out by another electron. When this does not happen, when the
cancellation is incomplete, is when there is magnetism. Cobalt, nickel, and
most importantly, iron, share this property.

The reason that the World Health Organization
would concern itself with electromagnetic fields is because of the threat to
health it causes. EMFs can cause brain
tumors, leukemia, birth defects, miscarriages, chronic fatigue, headaches,
cataracts, heart problems, stress. nausea, chest pain, forgetfulness, cancer
and other health problems. Some experts say that it is likely that up to 30% of
all childhood cancers come from exposure to EMFs. The Environmental Protection
Agency (EPA) warns "There is reason for concern" and advises prudent
avoidance".

The electrical basis for the magnetic
properties of matter basically is just the combination of the spin and electric
charge in an electron, which causes a small magnetic field to arise. When there
are many atoms, all the electrons are paired in energy levels, and, according
to the exclusion principle, which means the electrons can have opposite spins
and the magnetic fields cancel.

Magnetic field consists of imaginary lines of
flux coming from spinning electrically charged particles. Examples include the
spin of a proton and the motion of electrons through a wire in an electric
circuit. What a magnetic field actually consists of is somewhat of a mystery,
but we do know it is a special property of space. The lines of magnetic flux
flow from one end of the object to the other. By convention, we call one end of
a magnetic object the N or North-seeking pole and the other the S or
South-seeking pole, as related to the Earth's North and South magnetic poles.
The magnetic flux is defined as moving from N to S. Although individual
particles such as electrons can have magnetic fields, larger objects such as a
piece of iron can also have a magnetic field, as a sum of the fields of its
particles. If a larger object exhibits a sufficiently great magnetic field, it
is called a magnet. The magnetic field of an object can create a magnetic force
on other objects with magnetic fields. That force is what we call magnetism.
When a magnetic field is applied to a moving electric charge, such as a moving
proton or the electrical current in a wire, the force on the charge is called a
Lorentz force. When two magnets or magnetic objects are close to each other,
there is a force that attracts the poles together. When two magnetic objects
have like poles facing each other, the magnetic force pushes them apart.
Magnets can also weakly repel diamagnetic materials. The magnetic and electric fields are both
similar and different. They are also inter-related. Just as the positive (+)
and negative (−) electrical charges attract each other, the N and S poles of a
magnet attract each other. In electricity like charges repel, and in magnetism
like poles repel. The magnetic field is a dipole field. That means that every
magnet must have two poles. On the other hand, a positive (+) or negative (−)
electrical charge can stand alone. Electrical charges are called monopoles,
since they can exist without the opposite charge.
2 New Theories
1.
We cannot increase magnetism too much, or it
could be harmful to health
2.
The repelling of the same type of magnet makes
us want two of the same pole facing each other
3 New Questions
1.
How can we reduce magnetism enough for it to
not cause health issues?
2.
How can we make sure the magnetic field will
not catch other things?
3.
Is magnetism even an issue for these types of
cars? How can we determine this?
2 ideas
1.
We should use electromagnets in our invention
to increase efficiency and force
2.
We should use the properties of the Earth’s
electromagnetic field
