Is the North Pole the only magnetic pole of the earth?
The north pole of a compass needle points to a location we call 'Magnetic North'to distinguish it from 'True North'. Since 'unlike poles attract', the magneticpolarity of Magnetic North is obviously south.But when we talk about the Earth's 'north pole' or 'south pole', we're almostalways talking about the poles of its rotation, at 90° north and south latitude.Those points have no connection to the north and south magnetic poles, andcompasses don't point to them.
Why does the compas always point in the same direction?
The terms, 'Magnetic North' and 'Magnetic South', are used to distinguish these locations from 'True North' and 'True South'. It's very important to understand that they do not refer to the magnetic polarity at these locations. Unlike True North and True South, the actual locations of Magnetic North and Magnetic South vary over time.The ends of a magnet or compass needle are named after the directions in which they point (or, more accurately, the direction of the field along which they align) and, originally, were referred to as their 'North-seeking' and 'South-seeking' poles. The terms 'seeking' are now considered archaic and are no longer used, but the remaining terms 'north' and 'south', by convention, also define their magnetic polarities.In accordance with the law that 'like poles repel while unlike poles attract', this means that the magnetic polarity of 'Magnetic North' is actually a south, while the magnetic polarity of 'Magnetic South' is a north. In other words, the earth behaves as though there was a giant bar magnet, buried deep within its crust, whose south pole is located in the Northern Hemisphere and whose north pole is located in the Southern Hemisphere.Any answers that suggest that the 'North-seeking' pole of a compass is really a 'south' pole is completely incorrect and indicates a lack of understanding of the behaviour of magnets.Additional Comment[On modern maps, the north is at the top of the map. This was not always so, and in early times, the east was at the top. For sunrise was a reliable indicator. Hence the term 'to orient your map'. From the Latin oriens, literally rising. Similar conventions occur in several languages. And the Latin for Occident means 'setting'.]
A sentence using magnetic declination?
Your magnetic compass does not actually point north, it merely aligns itself with the lines of magnetic force at your location. These do not necessarily point to the North - they may differ by some tens of degrees. This difference is the Magnetic Declination. On hikers maps, you'll find that the true north of the map is shown as well as the magnetic declination at that region. The declination itself changes slowly, too slow for you to bother with its changing.
Are the magnetic North Pole and the geographic North Pole always the same distance apart?
Actually no. Magnetic north shifts over time. It has to do with the rotation of the liquid iron inside the earth. I can't remember the exact number but I think you can estimate true north by adding 5 degrees to your compass.
How is compass used for finding directions at unknown places?
It is basically a magnet and it will point to the magnetic pole (north) The compass is magnetized and the poles of the earth emit magnetic waves what attrach the needle in the compass to point away from South and towards North
How could you map the field around a magnetic nail?
??? don't know
What are the lines called that map out the magnetic field around magnetic?
They are called the magnetic field lines.
What are the lines called that the map out the magnetic field around a magnet?
They are called the magnetic field lines.
Are the lines that map out the magnetic field around a magnet?
no
What are lines called that map out the magnets field around the magnet?
They are called the magnetic field lines.
What did William Gilbert discover when he used a compass to map force around a magnetic sphere?
He found that Earth has a magnetic field also known as magnetosphere
What instrument measures changes in Earth's magnetic field?
You can show that the Earth has a magnetic field by looking at a magnetic compass.The north end of the compass points to the north magnetic pole, and does so everywhere on Earth. It does this by aligning itself to the Earth's magnetic field. If there weren't a magnetic field, then a compass needle would not point to any consistent direction.See related links.
What kind of waves are used in magnetic resonance imaging to map body tissues?
To map body tissues, MRI (Magnetic Resonance Imaging) uses a combination of techniques: a powerful magnetic field, and radio waves. Radio waves are utilized for mapping because they will not damage the body tissue.
Can magnetic field lines be detected by a compass?
The magnetic field can certainly be detected by a compass.The 'lines' are a handy human invention, and don't really exist, so you could not,say, trace out the lines with a compass, because they're not there.But place a compass next to a wire that's involved in any battery-operated (DC)circuit, and the compass absolutely goes crazy !
What is the value of earth magnetic field?
The magnetic field of planet Earth is very important for sustaining life. The magnetic field creates a magnetic map around the world, which birds use to navigate. Also do they create the magnetic north and south pole. But the most crucial thing about our magnetic field is that it protects our atmosphere from solar activity, otherwise our atmosphere would be blown away by solar wind and everything on this planet would die. This happened to Mars, which had oceans and rivers and an atmosphere billions of years ago, but when it's core dried up, it lost it's magnetic field by which the atmosphere was vulnerable and blown away. Causing the planet too become freezing cold and all water to vanish.
Does the compass needle point in the same direction indicated by the magnetic field maximum?
Your compass needle will align itself with the lines of magnetic force at your location. This will diverge from the simple 'earth monopole model' depending on the local magnetic field, and any local geomagnetic anomalies.On most topographic maps, the 'magnetic deviation' and its annual variance will be marked on the map legend. Where i am it is about 25 degrees east of the true magnetic north.
Why do orienteering maps have magnetic North Pole instead of the true North Pole?
That is because the map is used with a magnetic compass. Since the needle on the compass points in the direction of magnetic north it is easier to use the map with the compass if the lines drawn on the map indicate magnetic north.
