What is the function of liquid chamber in a magnetic compass?
The liquid is there to dampen the movement of the needle. Without the liquid, the needle would spin and jiggle about rapidly. Hence the need to slow the movement down - it makes the compass easier to use.
Does a compass use electricity?
no
What is the best material to use for a speed bag platform?
Luster of silk is one of the best materials that you can use to make the speed bag platform.
Use of rotameter with needle valve?
what is the proper procedures for cheking and adjusting the needle valve
How do you magnetise a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
Is it possible to use compass needle at the poles?
Yes it is possible to use compass needle at the poles
How will you distinguish magnets from non-magnetized magnetic material?
You can use a device that detects magnetism. A compass needle may suffice.
How local attraction affect the use of prismatic compass survey?
It deflects the needle / ring of the compass...........
What tool would you use to detect magnetic effects?
A magnetic needle meter, or a simple compass.

What is the difference between an Australian compass and British compass?
The needle of a compass must be free to rotate so that it can point to magnetic north. The magnetic field of the earth not only rotates the compass needle horizontally but also pulls one end down. If it pulls the needle down it can stop it from turning freely so on many compasses the needle is balanced for use in a specific zone. There are 5 zones. Austraila and Britain are in different zones. This means the needle may not be level if used in the other's zone. Needles are balanced by making one end of the needle longer or by adding weight to one end of the needle.
What is the arrow in a compass made of?
The compass needle is made of a small piece of magnetized steel, that in use aligns itself parallel with the lines of magnetic force at your location.In the northern hemisphere, by and large, the N painted end of the needle will point towards the North Pole.In the Southern Hemisphere, by and large, the S pole of the needle will point to the South Pole. (For it is the strongest there.)Because the compass needle will follow the lines of force, and these lines dip into the earth, compasses designed for use in the N hemisphere will have a small counter balancing weight to bring the needle to level.Analogously for compasses designed for use in the southern hemisphere.For people who wish to use their compass anywhere on the Earth, (such as military) they will have a slightly insensitive needle, and a more massive plate or dial.Having the dial (or card) immersed in a slightly viscous fluid will help steady the swinging of the needle.It is made from any magnetic material such as steel
How do you identify the north and south pole of a magnet?
Use a compass. It's needle points to the south pole of a magnet.
How do you make a circle with a compass?
If your unable to figure out how to work a compass its probably best not to use it.

What is the purpose of a boat compass?
The needle on a compass always points true north. In marine use, a compass can be used to adjust the path of a vessel so it stays on course. A compass can also help one detour from a charted course in order to avoid a storm or other hazard.
