can we use magnetic force to travel in space???

I have not read the article but this sound it weird enought I thought I mention it.\n\n\nBurkhard Heim claimed it is possible to convert electromagnetic energy into gravitational and back again, and speculated that a rotating magnetic field could reduce the influence of gravity on a spacecraft enough for it to take off.

In theory, a very light weight space craft with a very large area "sail" could use pressure from sunlight itself to accelerate. Note that it is the actual sunlight, as in photons, that exert the force, not the solar wind, which is a stream of particles from the Sun. The solar wind does not exert nearly as much force as the light does. Hard to believe, but true.

Yes if sufficient force is applied the force of impact will negate the magnetism. This is because the charged particles (electrons, neutrons, protons) will collide and confuse the flow of energy. Unless you have an elctromagnet then the magnetism will survive.\n\nSometimes if you drop a compass you will also make it useless as they are also magnetic

Technically no.  As you get closer and closer to the speed of light the weight of objects grows and grows so that eventually it will stop accelerating.\n\nOne thing that is possible is subspace, freespace, or wormhole travel, all of which are the same thing.  This is where space bends so that the distance is made shorter.  An example of this is traveling to the other side of the world.  You can go around the world, or you can go straight through the center (this is impossible), which distance is shorter.  To achieve subspace travel you must open up a big enough portal of quantum foam, or the space between the nucleus of an atom and its electrons.  We can not currently do this because we do not have the ability to make cold fusion which is the only 'safe' way to supply enough power.  Navigation, however, is a completely other story.\n\nhope this helps answer your question.

No! Earth has a power gravity core not a magnetic gravity core, the magnetic and Iron core is the weight density on spacetime providing gravity as some people including me theorise and include that to our major theories.

All things with mass (made of matter) have a gravitational pull.  Larger things, like planets, have a stronger pull.\n\nThe magnetic field is caused by the movement of metal under the surface of the earth.\n\nGravity is considered by scientists to be a weaker force than magnetism.\n\nThe magnetic field helps to block harmful rays from the Sun and we would probably fry if we had no magnetic field and no protection.\n\nOf course, if we had no gravity, we would have no atmosphere and would die much more quickly.\n\nDoes that help?

as far as i know of, yes.\n\nthink, the man made magnets create their own magnetic field and have always been exposed to the earths magnetic field. Reguardless of the man made one's position, they still emit the same pull towards each other based on their own magnetic fields. Just like magnets work in outer space, they should work at the north and south poles. (also, the man made magnets pull isn't effected when you connect multiple ones together so off of this example, they should work at the north and south poles also.)

It is not possible to escape from Magnetism or Gravity though you can counter it by some methods\n\nMagnetism---- If you have a magnet at one side, put a same kind of magnet opf equal strenght on the other side and with its like poles on the like side, both will repel each other, making a null point ie the point of no magnetism.\nIf you are on earth, a null point is formed where the earths magnetic field and the magnets field are of equal strenght. Here there is no effect of magnetism.\n\n\nGravity---- When you travel at a speed of (gR)^(1/2) from the earth's surface, you be at Orbital velocity and you can travel in an orbit around the earth, like the satellites. But if you want to reach escape velocity (2gR)^(1/2), then you'll escape from gravity.\n\ng- acceleration due to gravity\nR- radius of planet\n\nPlease make ithe best answer

Actually, no force is necessary to keep the earth moving in the vacuum of space.\nNewton's laws on motion cover it pretty well.\n"An object placed in motion, stays in motion until another force\nchanges it's motion". (I'm paraphrasing here but I'm sure you get the idea)\n\nIf you could float in space and throw a rock, it would just keep going in that direction until it finally hits something. As it goes by larger objects, the gravity from these objects may change the direction of the rock slightly but it would take a very large object (think planet or moon) to really change the direction of the rock dramatically.\n\nGravity is the force that simply keeps the earth in it's relative distance from the sun, counteracting the centrifugal force from our revolving around the sun, thereby keeping us from flying off in a tangent, never to be seen again.   ;-)\n\nI hope this helps you.\nGood Luck!

GOOD IDEA.\n\nEven better - why not build more of the Japanese train (there's a small one in the UK too) which travels on the +/- polarity of magnets along with an accelerator.\nThere is no friction at all with these, and, apparently, no limit to a top speed !\n\nThere are no environmental issues either.\n\nBig question though, would the oil/gas companies allow it, seeing it would destroy their business ?

I use one underground regularly.  The magnetic field pervades the whole planet.  Magnetic objects or rocks can distort the measurements, but they can at the surface too.\n\nEven if you were so deep underground that your compass was above the Curie Point and lost it's magnetism (in which case you would be dead as that is over 500 degrees), you could still use a fireproof electronic flux-gate compass, as the magnetic field is generated by the molten iron core (nobody is exactly sure how), so the field is present at all temperatures.

Hey I've always thought of it.\nIf you find one, just answer any of my questions in my Q&A (in order to contact me).\nGOOD QUESTION, anyway.\n\n\nI've always dreamt of using such a magnet for levitation.

NO.......magnetic monopoles havent been discovered yet.\nSo magnetism is still in accordance with Maxwell's equation,\ndiv(B)=0

that's sweet here i think is a link for a patent. I was thinking on how to make something like that, accelerating itself but i failed :P another of my questions was proven wrong leading me to the conclusion it is impossible for magnets to be used in mine.\n\nhttp://www.inventhelp.com/contactform_patent.asp?id=106&wcw=overture&GCID=S17330x002&KEYWORD=patent+office&MATCHTYPE=search

No.  It is scientifically impossible.  To move an object you must apply an unbalenced force.  What force is telekinesis?

Well even though humans have known about magnets for thousands of years, the real reason they work is still somewhat mysterious. Depending on how deep you want to investigate, it can be a very complicated phenomenon. \n\nA magnet is, at its foundation, caused by the movement of electrical charge (yes this is the Biot-Savart Law). When charges (like electrons for example) move, they produce magnetic fields. If a charge moves in a loop, it creates a magnetic field. The magnetic field can be basically represented by an invisible set of arrows in space, that point in a direction. In the case of the loop, the arrows of the magnetic field will point out of the loop for a positive charge moving counter clockwise (this is the so-called "right hand rule"), and into the loop for a charge moving clockwise (some pictures are in the reference attached). \n\nThe magnetic field has a "north" end and a "south end". The little arrows from our moving charge are pointing in the "north" magnetic direction, and away from the "south" magnetic direction. It is a mysterious and interesting property of electromagnetism that two objects with fields that oppose each other, i.e., the little arrows of the field do not line up, so either the north end of one field is facing the north end of the other field, or the two south ends are facing each other, repel, or resist movement of the two objects towards each other with some force. \n\nOn the other hand, if the little arrows line up, the two objects attract each other with some force. \n\nThe little arrows are aligned along the so-called "magnetic lines of force". \n\nThe forces that result from magnetic fields (and for that matter, electric fields) are fundamental forces, and part of the four fundamental forces of the universe (strong, weak, electromagnetic and gravity). It is believed that these forces are caused, at their base, by particles passing "messenger particles" back and forth. In the case of electromagnetism, the messenger particle is a photon. How this actually works is still somewhat poorly understood, and is involved with the world of quantum mechanics, which is very counterintuitive but interesting. \n\nHowever, what is important is that we understand it well enough to make models of magnetism, and to make predictions based on those models which we can verify and use. All of electricity and electric motors are based on our ability to design systems with magnets and to be able to build and use them.

Yes, this is the principle that motors work off of.  It is also used for other purposes, such as launching roller coasters.  While it is possible to control the strength of the magnetic field in an electromagnet, permenant magnets cannot have their fields controlled.  So, in order to control the force between two magnets, only one of them must be controlled, so one may be an electromagnet and the other a permenant magnet.
