What is the difference in magnetic North &  the True North . Any one from the Aviation field please clarify?

True north would be a line from your position to the geographic north pole.\n\nMagnetic north is a line between your position and the northern magnetic pole.  \n\nSince the northern magnetic pole does NOT coincide with the geographic north pole (IIRC, it is somewhere in northern Canada), there is a difference between those two lines.  The magnitude of that difference depends on precisely where on the earth you are standing when you take your measurement.\n\nThat's why, on all good topographic maps, they have an indicator of both magnetic north and true north, so you can apply the appropriate correction to navigate with a compass.  Of course, global positioning systems are making that problem a non-issue (if you can "see" the satellites . . .).

It all depends in what sense. With magnets you have a north and a south pole, same as the earth. different poles attract, same propel away. In terms of electricity you have negitive and postive thouch both of them together and you get a spark.

Whe teaching basic navigation we cover the difference between magnetci and grid north.  Previous answer here is good.  But I would like to add the ditty we use to remind people to apply the variation figure when moving from the map to compass and vice versa.\n\nwhen taking bearing from the map and putting onto the compass add the variation (From grid to mag ADD)\n\nWhen applying a compass bearing to the map then take the variation off. (From mag to grid get rid).\n\nAlso the amounbt of variation and its direction will vary depending on where you are on the earth.. In the UK the magnetic variation is about 6 degrees West.\n\nWe use the ditty "Variation East Compass Least (ie take the figure off the magnetic reading)- Variation West Compass Best." (ie add it to the magnetic reading.)

Yes it's true. It is called Magnetic Hill ,in New Brunswick, Canada. It is neither magnetic nor a hill, but an optical illusion that makes one seem to be going up hill when in truth one is actually coasting down grade. It is all due to the surrounding countryside.

The Earth's center contains a lot of molten iron; due to Earth's rotation, it rotates too, thus generating a magnetic field. It's bit more complicated, but in a nut that's the explanation.

Earth's magnetic field, among other things.

Not that big!\n\nMagnetism is stronger than gravity by order of thousands.\nThe earths magnetic field is bigger and stronger than the earths gravitational field.\nMagnetism is stronger than gravity otherwise you would not be able to pick things up with a magnet

The directional North pole of the earth is a magnetic south pole, this is because the north end of a compass points north, and opposites attract, therefore north is...south.\n\nMagnetic lines go from south to north i think, sorry havn't taken electricity/mag class in so long...\n\nanyways, if my thining is correct than it would point towards the directional south\n\ni'd choose "down"

Its not so much one pole attracting the needlepoint so much as the entire magnetic metal beneath the needle aligning to the magnetic field lines*. North and South are just directional names; the most powerful magnet at the time magnetism was discovered was the earth, so naturally, they used the locations of the Earth's poles to name every magnet's pole.\n\n*Magnetic field lines are lines of force connecting the North and South poles of every magnetic object. Place a magnet under a piece of paper and sprinkle iron filings on top, and you'll be able to 'see' them. \n\nThe magnetosphere is the name given to the Earth's magnetic field, which extends into space and gives us protection against much of the charged particle radiation from the sun. This 'solar wind' interacting with our magnetosphere is what causes the auroras over the poles.

It would want to point at the ground. By the way, the magnetic pole is in northern Canada, pretty far from the geographic pole. At the geographic pole it would point south, to the location of the magnetic pole.

Having No Magnetic North or South Poles in Outerspace- I would have to say it would be "dormant" and read the same as it read on earth the minute you left the ionosphere \n( 6 miles Up = outerspace).

Wind is a result of uneven heating of the earth. Hot air moves up and cold air moves down due to hot air being less dense than cold air. This moves the atmosphere around (There is also an effect from the Earth's rotation). \n\nSome other answers about magnetic fields may have been referring to "solar or magnetically charged particle wind," but certainly not common atmospheric wind. Atomospheric wind (hot air vs. cold air and the rotation of the earth) does not affect radio waves in any appreciable way.

See, when you read a compass it does not point to true "north" it points (north) to the MAGNETIC pole which currently is in Hudson Bay. SOO if you're reading a map it will give you true north and if its a good map, magnetic north. Most people use maps that use true north. THEREFORE when you're "on the ground" and trying to find your way around and you have a map that points to Magnetic north and your map uses true north you have to take that into account. So we use declination on our compasses so that they guide us more towards true north, rather than into hudson bay. So what you will notice is that a map showing declination over the US is that people BELOW Hudson Bay use little declination because true north is basically where magnetic north is, but way out in Washington and Oregon you have to use more declination because your compass needle will be pointing more easterly that it should.....make sense?

Earth's magnetic field constantly fluctuates to some degree (it's weakened by about 10% since the 19th Century), but the majority of geophysicists see no hard evidence that the field is about to reverse like it's done in the past.\n\nEven should it reverse, the whole cycle takes thousands of years, and still would have little effect on our electrical power systems. Nor would planes fall from the sky, although reliance on magnetic compasses would have to be adjusted.\n\nGod should be spelled B-I-G B-A-N-G\nPBrax@netscape.com

The pole in the north direction of earth is the south magnetic pole of earth's magnet.\n\nThe position of magnetic pole is changing but not the pole itself. If the pole cahnges then the magnetic needle in the compass will deflect in the opposite direction.

Sorry, but as far as I can tell, it doesn't exist.\n\nThen again, I know nothing about this area of interest.\nI like enio_giacomini's answer. Go with that.\nThen again, he answered that "magnet" question with "In center," which makes no sense at all.  Whatever. Your call.

First there are 3 north poles. There is magnetic north which your compass will point to, There is the North Pole the earth rotates on and then there is North which would be the top of the earth as compare to the sun and its orbital plane. We can also refer to north based on the position of the galaxy and assigning one end as North and the other as south. North and south poles are used in navigation after the discovery of the compass needle always pointing north.
