The magnetic north pole lies a few hundred miles away from the true North Pole. D. The compass is an electromagnet that is charged by rubbing when the needle is turning. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. The compass is made of magnetic material. People who use compasses know just how much to change course if they want to travel to the true north or south--or anywhere in between. It turns out that you can think of the Earth as having a gigantic bar magnet buried inside. Because the Earth's magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field. People who use compasses know just how much to change course if they want to travel to the true north or south--or anywhere in between. And forget to subscribe the channel. In fact, even if you go south of the equator and quite close to the south pole, the compass will still point to the north … A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). The north side of the compass needle is actually the south pole of the magnet, which is why it is attracted to the Earth's north pole. All Rights Reserved, In a divided America, Lincoln’s words of healing ring true, Abraham Lincoln worked to rebuild a fractured nation ‘with malice toward none; with charity for all.’, Sione Takitaki interception earns shoutout from LeBron James, Porter Gustin lays out for pick. Why does a compass always point to the north? Hence, a freely suspended magnetic needle point in geographic north-south direction. The earth’s magnetic force pulls a compass needle in a north-south direction. Imagine there is a huge bar magnet inside the earth s crust. Therefore, even though a compass always points north, it does not always point toward the true north. So the lines of flux from the needle line up along the direction in which the Earth's magnetic flux is travelling -- and thereby points towards the North pole. In most places a compass needle does not point exactly north. The magnetic north is the geographical south and vice versa. Magnets operate on the principle of poles. The reverse is true for the south side of the compass needle, which is actually the north pole of the magnet and is attracted to the Earth's south pole. It points to magnetic north. In other words, a compass detects slight magnetic fields created by any object. - vanessa trujillo (age 11) ampa fl u.s.a. A: Vanessa - There are two important things that make compass needles point the way that they do. A compass and a map are essential tools when hiking in the woods. This means that all other compass points will indicate the corect direction. But they are sure that a compass needle lines up with the field. compass always point north because not in the east nor to the west or south. ScienceOnline Recommended for you. Therefore, even though a compass always points north, it does not always point toward the true north. A compass only points toward a north magnetic pole. Man has used compasses for navigation since approximately the 10th century. The magnets inside compasses are drawn to the magnetic North Pole, which is about 1,000 miles south of the actual North Pole. B. Use of a Compass Since the north seeking pole of a compass always wants to point north, then the compass could be useful in helping us navigate. When it lines up, one end of the needle points northe and the other points south.But don't expect to reach the North Pole if you travel in the direction your compass points. Prior to compasses, people relied on landmarks and the stars for navigation. Compasses first appeared in China but quickly spread to India and Europe. It tells direction because the earth acts as a huge magnet. Therefore, even though a compass always points north, it does not always point toward the true north. Scientists aren't sure why. You can use a map to do that. When the compass is used, the rose can be aligned with the corresponding geographic directions; for example, … That idea combined with the concept that when we look up we see the stars, contributed to north being placed up at the top of maps, with words and symbols being placed relative to that viewpoint. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. To explain why the compass needle points to magnetic north, there is only an assumption theory. It can do this because the outer core is liquid. Earth's North Magnetic Pole is actually the south pole of the Earth's geographic poles and vice-versa. A compass points to magnetic north, and Europeans, like other cultures long before, noticed that the earth spins on an axis that is relatively pointed at the north star. This is a educational video which explains some curious questions. Hold a compass in your hand and it will point to the Earth's north pole. It is called the standard bar magnet assumption theory. Photo: A magnetic compass points north because it aligns itself with the magnetic field produced inside Earth. D) The compass is an electromagnet that is charged by rubbing. Because the needle always points north (magnetism). A. If you point the north side of the compass away from you the compass will point south. It's actually a little magnet.
