a compass has a magnetic point which points to the north pole.
well yes but....a compass has a magnetic needle inside it which attracts it self to the earths magnetic field. it may not actually point to the norht pole but actually to the earths magnetic north pole
Very easy, but difficult without visual aids. Hard to put into text! What is it you need to know???
How to find North?, how to take a bearing?
Let me know & i will try my best to explain in text!
The key mechanism behind a compass is the magnetic field generated by the Earth's core. This field results in the North pole exhibiting a South magnetic polarity and the South pole exhibits a North magnetic polarity. While this may seem like a contradiction, remember that magnetic opposites attract. Whenever you construct a compass, the needle that points to the North must be made from an object with a North polarization. In the Northern Hemisphere, this needle will be attracted to the South Polarity of the North Pole and point North. In the Southern Hemisphere, the needle will be repelled by the South Pole and thus will also point to the North.
When navigating with a compass, one will have to be careful to remember that Magnetic North and Geographic North are not the same thing. The magnetic North Pole is currently located to the West of the Ellesmere Island in Canada. Therefore, while a compass points close to Geographic North, as you get closer to the actual North Pole, it gets even less accurate.
In addition, the location of this magnetic pole is not permanent. Current observations show that it is actually moving North at 41 km/year (but not even that speed is constant). Also, due to complex interactions at the Earth's core, the polarity of this field also switches on average every 300,000 years. One day, all compasses will actually point to the South Pole!
A compass contains a needle which shows the holder north and south when the needle turns. A compass contains a lightweight magnet and fricitionless bearing to connect with the earths magnetic field otherwise the needle cannot be turned.
It is a thing that helps you not to get lost. Its needle in the middle is a magnet, so it will be attracted to the lodestone and tells you which direction is where.
Magnetic fields are mostly influenced by varying electric currents and various kinds of magnetic material. Electric currents combined with quantum properties cause the field to spin.
In short, the needle of the compass is a magnet. Because there are large deposits of iron in the far north, the magnet is attracted to them and points north.
the way a magnet is used in a compass is that it would always point to the earth magnet north instead of the north pole
Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.
The Earth has a magnetic field approximately like a magnetic dipole, with the magnetic field S pole near the Earth's geographic north pole and the other magnetic field N pole near the Earth's geographic south pole. A compass can determining direction relative to the Earth's magnetic poles by using a magnetized pointer (usually marked on the North end) which is pivoting free to align itself with Earth's magnetic field.
on a compass it caused the compass to point to the magnet instead of magnetic north, I think that South will point to the magnet (if I remember correctly) You can get around this by using our patent which allows a magnetic radio speaker in a radio direction finder to sit directly next to a compass - by aligning the radio speaker to sit directly south of the compass it does not effect the accuracy.
i have a saracom magnetic compass & it has big bubble inside. i have to remove bubble.what type of fluid i have to use, compass make: SARACOM model: MC180
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.
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 !

One affect may be that people today would be going north when they think they are going south. It would affect the compass that they may be using
No a compass rose is on a map showing all of the Carnal Directions (north South East west) and a Compass is navigational device used to find your direction by using the earths magnetic poles
It is a device for determining aircraft direction using the magnetic field of the earth. See link to Earth inductor compass

The magnetic field points north and there is a south facing magnet will point north so and the earth is on a 33.3 degree axis. This is why is will point to Canada.
Yes. I can be done using iron filings and a clear piece of plastic. Pour on the iron filings, put on the plastic, and then the magnet. The iron filings should form the shape of the magnetic field around it. If that does not work, here is a link to a picture... http://www.fi.edu/htlc/teachers/lettieri/magneticfields.jpg Hope that helps.
You can detect the presence of a magnetic field using a compass, which will align itself with the field lines. Other devices such as magnetometers can also detect and measure magnetic fields accurately. Additionally, certain materials, such as iron filings, can visualize magnetic field patterns when sprinkled around the area.
