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.
Are the lines that map out the magnetic field around a magnet?
The lines that map out the magnetic field around a magnet are called magnetic field lines. These lines indicate the direction of the magnetic field and its strength at different points around the magnet. Magnetic field lines are closest together where the magnetic field is strongest and they form closed loops that do not intersect.
What are the lines called that the map out the magnetic field around a magnet?
They are called the magnetic field lines.
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
How a compass can be used to trace the magnetic field of the magnet?
A compass can be used to trace the magnetic field of a magnet by placing the compass near the magnet. The needle of the compass will align with the magnetic field lines, allowing you to visualize the direction of the field. By moving the compass around the magnet, you can map out the shape and direction of the magnetic field.
How size of magnetic field is measured?
The size of a magnetic field is typically measured using a device called a magnetometer. This device can detect and quantify the strength of a magnetic field in terms of its magnetic flux density, usually measured in units of tesla (T) or gauss (G). Magnetometers are widely used in various fields such as geophysics, engineering, and environmental monitoring to measure and map magnetic fields.
What is the Magnetic Field of earth's crust?
Earth's magnetic field is not in its crust. It passes through the crust, but it is generated by the differential motion of the inner and outer core. The core is mostly iron and nickel. This creates huge dynamo and generates our 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.
How can brain activation produce a magnetic field?
Any material that can conduct electricity can produce a magnetic field. The brain uses tinny amounts of electricity to move messages around itself so the brain produces a very small magnetic field that Medical Doctors using very sensitive equipment may be able to detect
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 !
