Table of contents

  • Magnetic ideolodgy
  • ElectroMagnets
  • Emps
  • types of magnetism
  • NASA's magnetic portals
  • Large hadron collider
  • MAGNETS 101

Magnetism Ideology

  • The basic domains in the electrons of a magnetic material are in certain patterns that are are all aligned So that the energy goes in one way forming the attraction and repulsion effect
  • Magnets can be Permanent or temporary
  • permanent magnets are magnets that cannot(unless extreme heat or pressure is applied) be undone
  • Temporary Magnets are magnets that are made when a magnet touches something else and then can pick up other objects.

ElectroMagnets

  • Electromagnets are the type of magnets that use electricity
  • The magnet uses coils to condense the voltage and makes a magnetic field
  • The more coils there are or the more voltage there is the more the magnetic effect is
  • The less coils there are or the less voltage there is the less the magnetic force is

EMP

  • an emp is an electromagnetic pulse that launches outward when dropped by a bomb that disrupts or destroys the electronics in the surrounding area
  • The area one can cover is massive
  • if china where to drop one on Kansas city, it would enhilate electronics on the east and west coast also parts of canada and mexico
  • That was one of the threats of china over the years
  • Scary Stuff

tYPES OF MAGNETISM

  • dIAMAGNETISM
  • PARAMAGNETISM
  • FERROMAGNETISM
  • ANTIFERROMAGNETISM

Diamagnetism

  • This type of magnetism is a non permanent type of magnetism
  • This type of magnetism can be used to levitate objects such as beds
  • They can be levitated with opposing fields on all sides and a strong steady magnet on its base
  • if you have a spare 1.8 million dollars just laying around you can buy one
  • It is magnetism that happens when a group of ferromagnetic materials and they group together and form a field of magnetism
  • it is very strong and temporary

Paramagnetism

  • It is a non-permanent type of magnet
  • It is a very unstable type of magnetism that can be disrupted with very small temperature movements which cause the valence electrons in the atoms themselves to vibrate and lose its magnetism
  • paramagnets are basicly when you would take a nail and put it on a magnet, the nail would become paramagnetic

ferromagnetism

  • ferromagnetism is the basic type of magnetism
  • The magnets are kitchen magnets, clip on mirrors, bar magnets, etc.
  • it happens when the electrons in the material allign

antiferromagnets

  • This type of magnet was only recently found and are used in many extreme experiments such as the large hadron collider
  • These magnets can only function at extremely low tempatures
  • they are called superconductors and are very strong
  • it is a temparary magnet

The large hadron collider

  • the large hadron collider is an experiment that could have completely revolutionized science or destroyed the earth
  • the experiment shoots 2 particles through a series of 1232 dipole magnets (bar magnets) and 392 quadropole magnets(2 bar magnets that are faced inward) to propel to see what happens when they hit and all the magnets are antiferro magnets
  • This is compared to hurling 2 needles across the Atlantic ocean and making them hit

how it could have destroyed earth

  • The collider's main purpose is to prove the big bang theory
  • They collide singular particles at next to the speed of light
  • This could have recreated the billionth of a second after the big bang.
  • Or it could have created a miniature black hole and absorbing the entire solar system.
  • that would have been bad.

how could it have revolutionized science

  • the collider is an atom splitting device that hurls a single atom through a 23 kilometer tube and smacks another atom and splits.
  • It uses very powerful and unstable antiferromagnets that are cooled to extreme temperatures using liquid helium
  • Using this technology humans could debunk the big bang theory by showing what happened

Perpetual Motion Machine

  • This idea for a machine that needs no energy to make energy began with Sir Isaac newton and he tried to disprove the fact that that machine could be made and said it was imppossible
  • He said that due to gravity and friction, there is to much fighting against it
  • Due to recent technology(Magnets) this machine can happen.
  • although you still cannot make force higher than its original force without adding more force, recent studies suggest that the energy given off by a magnet could power one of these machines
  • If you created one of these machines, Mr. Laarman says ''you would have so much money bill gates would have nothing on you''

NASA's Magnetic portals

  • These portals to the sun are not really portals
  • The portals are made when the magnetic field of earth are combined with the solar flares of the sun and create a magnetic tube of energy going back and forth between the sun and the earth
  • They pop up multiple times of the day and are very unpredictable
  • NASA still does not know how to find them perfectly
  • The way they find them at the moment are finding the diffusion zones in the electrons of the magnetic field
  • It is not very easy considering that the areas of diffusion are completely invisible to the human eye
  • They could possibly used in the future for closer observation of space and maybe a new form of transportation.

Magnets 101

  • Magnets can be in different forms,bar and horseshoe, but every type of magnet has 2 poles, north and south.
  • even if you cut a magnet in half, it will still have 2 poles.
  • Magnets can be demagnetized with extreme heat or pressure. The only mystery i have with that is the center of the earth, it has both heat and pressure. ???
  • the earths magnetic field is getting slowly, over thousands of years, being switched and will eventually be opposite
  • Some scientists believe that the dinosaur died out because of a sudden drop in the magnetic field, thus causing all the dinosaur to all at once get cooked or really sunburned. there is not alot of evidence supporting it,but it makes sence
  • Almost all animals that migrate have been known to use magnets
  • Magnets have been found to streghten your immune system and weaken it

In conclusion

  • Magnets are a very complex sytem and can be made or found, they can be used in war or used to float a 1.8 million dollar bed
  • there are 4 types of magnets that can be used in different ways
  • You can also use mmagnets to do experiments that could end humanity
  • Magnetism can also be used for a direct trip to the sun
  • Magnets are cool
  • Magnets can be used to make a perpetual motion machine that could wipe out the need for fossil fuels and need for new renewable energy sources
  • mangets are cool
