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

∙ 14y agoVery 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!

∙ 14y agoThe 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!

∙ 10y agoA 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.

∙ 9y agoMagnetic 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.

∙ 15y agoIn 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.

∙ 11y agothe way a magnet is used in a compass is that it would always point to the earth magnet north instead of the north pole

How yo find the magnetic field of earth at a particular place?
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.
How the compass works?
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.
Effects of this magnetic field on a compass or closely spaced objects?
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.
What type of fluid using in saracom magnetic compass model MC180?

What are the problems of using a magnetic compass at sea?
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.
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 would be the efffect on people if the earths magnetic field fliped?
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
Is a compass rose and a compass the same?
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
What is the function of the earth induction compass?
It is a device for determining aircraft direction using the magnetic field of the earth. See link to Earth inductor compass

Why does the N pole of a compass points toward northern Canada using the terms magnetic pole and magnetic field?
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.
How do you find the shape of a magnetic field using a compass?
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.
How can you detect the presence of a magnetic field?
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.
