No. True north is the direction of earth's pole, 90 degrees north latitude. The pole is the axis upon which earth rotates. Magnetic north is the magnetic pole generated by the vast reservoirs of metal within the body of the earth. Magnetic north moves a little because the earth is very geologically active.
False. The Earth's magnetic fields are constantly shifting, and have been at widely different points over the Earth's history. The North Pole (geographic) is defined by the Earth's spin, and does not appreciably change over millions of years.
A compass points towards magnetic north, which is the direction that a magnetic needle aligns itself with the Earth's magnetic field. This is not the same as true north, which is the geographic North Pole. The difference between magnetic north and true north is known as magnetic declination and varies by location.
No. However, "magnetic north" is equal to true north for certain PLACES. The magnetic north pole is a slowly-wandering point which is currently in northern Canada. A line drawn from the north pole to the magnetic north pole, when extended through the rest of the world, defines a line of zero "magnetic variation", the amount by which magnetic north differs from true north. Most navigational maps are overprinted with lines of equal magnetic variation, and a navigator who neglects to properly apply the magnetic variation will become quickly lost.
False. Magnetic field lines curve out from one pole, travel through the surrounding space, and then re-enter the magnet at the opposite pole.
True North is the real North, following along the lines of longitude which converge at the North Pole, the farthest geographically North point on the planet, and the rotational axis of the planet. Magnetic North and Compass North are both the same thing, with the compass pointing along Magnetic North. Magnetic North however, is not the real North. If you were to follow your compass as far North as it could point, you would end up on the Prince of Wales Island in the Northwest Territories of Canada, over 1,500 miles away from the North Pole. Magnetic North can be adjusted to True North on your compass by knowing the local magnetic variation of your area and adding/subtracting accordingly. A third North is Grid North, which follows the Grid Lines on a standard map. At the South Pole, every direction is True North, so Grid North is used instead and can be found by following the Prime Meridian northwards. Hope that helps.
False. The Earth's magnetic fields are constantly shifting, and have been at widely different points over the Earth's history. The North Pole (geographic) is defined by the Earth's spin, and does not appreciably change over millions of years.
False. Opposite poles attract. Same poles repel.
no It points to magnetic north, which is not exactly the same as true north.
A compass points towards magnetic north, which is the direction that a magnetic needle aligns itself with the Earth's magnetic field. This is not the same as true north, which is the geographic North Pole. The difference between magnetic north and true north is known as magnetic declination and varies by location.
False. Magnetic poles and domains are different concepts. Magnetic poles refer to the regions of a magnet where the magnetic force is concentrated, while domains are regions within a magnetic material where the magnetic moments of atoms are aligned in the same direction.
It is measured exactly the same in the Southern hemisphere (no difference between the two hemispheres). It is the difference between magnetic north and true north and it varies all over the globe. Magnetic declination (also called magnetic variation) is positive when magnetic north is east of true north (clockwise) and it is negative when magnetic north is west of true north (anti-clockwise).
Because compasses have better things to do.
Nothing. The truth is, they have always been different.
True north relates to what we consider the north pole. However the axis on magnetic terms isn't in the same location. Magnetic north is still north but there is an angle difference between the two.
The magnetic north on a compass is the direction that aligns with the Earth's magnetic field. This direction may not be the same as true north, which is the direction towards the North Pole. Magnetic north can vary slightly depending on your location on the Earth's surface.
because it to differentiate between magnetic north and its self true north this is because every 12000 years or so the magnetic poles of the earth switch sides so if you were to use a compass it would point south as of next year some time. Also true north does actually change to but only in accordance to the movement of the earth and in any case stays roughly in the same direction true north and magnetic north are rarely if ever the same.
