Why is it difficult to get an accurate bearing with a magnetic compass near the poles?

It can vary but i will give one reason. You might be near a magnetic metal which will interfere with what you are are trying to do, iron for example or steel so stay away from magnetic metals.

Answer'Magnetic North' is a location or, more accurately, a direction. It does not describe its magnetic polarity. Since the north(-seeking) pole of a compass points towards Magnetic North, and since unlike poles attract, then the magnetic polarity of 'Magnetic North' is south.Wiki User
∙ 12y agoIt is because where the geographical north is there a bar magnet's south pole is there and where geographical south is there a bar magnet's north pole is there.This is because the earth acts like a magnet.That is, the earth's north pole and a bar magnet's south pole attract each other and the earth's south pole and a bar magnet's north pole attract each other.

∙ 9y agoThe Geographic / True North (as shown on globes) is not the same as the magnetic north.
Quote from a website:
True North is the direction of a meridian of longitude which converges on the North Pole.
Magnetic North is the direction indicated by a magnetic compass. Magnetic North moves slowly with a variable rate and currently is west of Grid North in Great Britain.

∙ 14y agoAll longitudes will join at north pole so which longitude value we will assign to the north pole or southpole... So we need to use different method to accomplish this purpose.

It's not difficult! Use a compass. It's needle will point to the magnet's south pole.

Is a compass accurate?
the compass can be very accurate once the correct steps are taken when using it =) ty
Does a compass point true north magnetic north or at the north pole?
North Star points at True North, you can use a compass and north star to see how far off magnetic north is from your location. .
What is the The north magnetic pole of a compass needle is attracted to the magnetic pole of the earth.?
The needle on a compass points to the North Magnetic Pole. CommentA compass points to Magnetic North, not to the north magnetic pole. They are two different things -the first is location, the second is magnetic polarity.
Which pole of a compass magnet is attracted to earth's magnetic north pole?
The pole of the compass that is attracted to the earth's magnetic north pole must be a south magnetic pole. But here's the thing. In the compass, the south magnetic pole of the needle is marked "N" because that end of the compass needle points to earth's magnetic north. The only way the needle can point to earth's magnetic north is if that end of the needle, the one marked with an "N" on it, is a magnetic south pole. It almost seems counter intuitive, but think it through and it will become clear.
Does a compass needle line up perpendicular or parallel to a magnetic field?
A compass needle will align itself with a magnetic field. It will want to lie along the magnetic field lines, or lie parallel to the lines of force of the magnetic field it is interacting with.
What is magnetic bearing?
It is a bearing (a direction) based on a magnetic compass reading.
What is the function of fore and aft magnet in a magnetic compass?
The fore and Aft magnets reduce the effect of the ships steel on the compass, so you get a more accurate bearing.
What are the advantages and disadvantages of compass survey?
advantage it helps u know the direction of your measurement in relation to magnetic bearing disadvantage it is affected by the weather

What are the problems of using a magnetic compass at sea?
A magnetic compass can be influenced by surrounding metal. For instance, take a compass bearing when your pocket knife is in your breast pocket, too close to the compass, or there is an underground metal water pipe near by, may cause an error in your compass reading. Even magnetic (iron) rocks you are standing on, can cause a wrong reading. When taking a magnetic bearing, leave your metal framed rucksack to one side.
Why gyro compass is used in ships instead of magnetic compass?
Because a ship is made of metal, which can affect the accuracy of a standard magnetic compass. Also, a gyrocompass is is better able to point to the true north, which is more accurate to navigation than magnetic North, which is not actually true North. Link below:
Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
What is local attraction on compass survey?
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.
What is 271 degrees true as a compass bearing?

How do you prevent undue magnetic influences on a compass?
Preventing other magnetic fields from affecting a compass is difficult, because the earth's magnetic field is relatively weak. Just in the home there are many things that can influence a compass, from the electrical wiring to the loudspeakers of a hi-fi. The best way to avoid these influences is simply to keep the compass far enough away from them. However, a magnetic shield can be built by simply housing the compass in a hollow iron container, but this will obviously also shield the compass from the earth's magnetic field.
What instrument is used for determining direction?
A compass. The North magnetic pole is in the direction of the N on the compass. Therefore, the North magnetic pole is in fact a magnetic field south pole since it *attracts* the north magnetic field pole of the compass magnet.
