If the magnetic North arrow in the declination diagram is to the left of the North grid line then what should the compass reading be?

What do you use to find true north?

You need to know the variation (also referred to as declination) for your location. Once you have that, you add East variation (or plus) to your magnetic compass reading, and subtract West variation (or minus) from your magnetic compass reading to get true compass reading. To find North, simply line your magnetic compass up so that the needle is on North and then either add or subtract your variation to get the true North reading. See the links below to find the variation for your position.

If you were in Uruguay and looked at your compass which way would the needle be pointing?

It depends which direction you're facing, it has nothing to do with where on the planet you are.WRONG ANSWER! Regardless of WHERE you are, or WHICH way you are looking, the compass needle will point to the NORTH. Not to the NORTH POLE mind you, but to the MAGNETIC NORTH, which is a little bit off from the TRUE NORTH and also MOVES a little bit every year. This is called VARIATION and depending on where you are, the TRUE NORTH may be to the right or to the left of where the compass needle points. Your reading will also be a little bit off to one side or the other, depending on which direction the needle is pointing (hey, nobody's perfect), but this is predictable and can be measured when the compass is calibrated (a process called swinging the compass). This is called COMPASS DEVIATION (don't think deviate now...) Another change may happen if you are going from West to East or viceversa AND you are accelerating or deccelerating, in which case the needle will lag. Last but not least, if you have any kind of magnetic interference near the compass, like a screwdriver with a magnetic tip, oh well then... the needle may be pointing God knows where.Northnorth because that's what way compasses point.

What do compass rose mean?

If a person is traveling they would need to know how to read a map, and what the symbols mean. The Compass Rose, is a compass. It gives a map reading direction, from where they currently are, to their end destination.

they are measured in degrees

How do magnets work?

Magnets have magnetic fields that attract items containing iron. Some of the substances attracted to magnets include iron, nickel, and steel. To understand a magnet you must first understand the magnetic field. A magnetic field is created as the result of moving charges such as electrons. A magnet's magnetic field either attracts or repels certain metals, as well as other magnets. A magnet has two ends that are referred to as poles. One pole is called north and the other one is referred to as south. To attract magnets to each other, you have to place opposite ends of two magnets near each other. Placing like ends of two magnets near each other causes the opposite to occur; the two magnets repel each other. A magnet is any object that has a magnetic field. It attracts ferrous objects like pieces of iron, steel, nickel and cobalt. In the early days, the Greeks observed that the naturally occurring 'lodestone' attracted iron pieces. From that day onwards began the journey into the discovery of magnets. These days magnets are made artificially in various shapes and sizes depending on their use. One of the most common magnets - the bar magnet - is a long, rectangular bar of uniform cross-section that attracts pieces of ferrous objects. The magnetic compass needle is also commonly used. The compass needle is a tiny magnet which is free to move horizontally on a pivot. One end of the compass needle points in the North direction and the other end points in the South direction. The end of a freely pivoted magnet will always point in the North-South direction. The end that points in the North is called the North Pole of the magnet and the end that points South is called the South Pole of the magnet. It has been proven by experiments that like magnetic poles repel each other whereas unlike poles attract each other. What is a magnetic field? The space surrounding a magnet, in which magnetic force is exerted, is called a magnetic field. If a bar magnet is placed in such a field, it will experience magnetic forces. However, the field will continue to exist even if the magnet is removed. The direction of magnetic field at a point is the direction of the resultant force acting on a hypothetical North Pole placed at that point. When current flows in a wire, a magnetic field is created around the wire. From this it has been inferred that magnetic fields are produced by the motion of electrical charges. A magnetic field of a bar magnet thus results from the motion of negatively charged electrons in the magnet. Just as an electric field is described by drawing the electric lines of force, in the same way, a magnetic field is described by drawing the magnetic lines of force. When a small north magnetic pole is placed in the magnetic field created by a magnet, it will experience a force. And if the North Pole is free, it will move under the influence of magnetic field. The path traced by a North magnetic pole free to move under the influence of a magnetic field is called a magnetic line of force. In other words, the magnetic lines of force are the lines drawn in a magnetic field along which a north magnetic pole would move. The direction of a magnetic line of force at any point gives the direction of the magnetic force on a north pole placed at that point. Since the direction of magnetic line of force is the direction of force on a North Pole, so the magnetic lines of force always begin on the N-pole of a magnet and end on the S-pole of the magnet. A small magnetic compass when moved along a line of force always sets itself along the line tangential to it. So, a line drawn from the South Pole of the compass to its North Pole indicates the direction of the magnetic field. # The magnetic lines of force originate from the North Pole of a magnet and end at its South Pole. # The magnetic lines of force come closer to one another near the poles of a magnet but they are widely separated at other places. # The magnetic lines of force do not intersect (or cross) one another. # When a magnetic compass is placed at different points on a magnetic line of force, it aligns itself along the tangent to the line of force at that point. These are just some of the basic concepts of magnetism. One cannot possibly grasp the depth and appreciate the versatility of magnets without reading more about the uses of magnets, the Earth as a huge magnet and electromagnetism among other things.
