Why should a compass be held flat?
A compass should be held flat to ensure that the magnetic needle can move freely and accurately point towards magnetic north. Holding it flat also helps prevent the needle from sticking or getting caught on surfaces, which could result in inaccurate readings.
What do the poles of a magnetized needle on a compass align themselves with?
The poles of a magnetized needle on a compass align themselves with the Earth's magnetic field, pointing towards the magnetic north and south poles. This alignment helps the needle to indicate the direction of north.
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 work best when close to magnet?
Yes, a compass works best when it is close to a magnet because the magnet helps align the compass needle with Earth's magnetic field. The closer the compass is to a magnet, the stronger the magnetic force acting on the needle, making it easier for the compass to point in the correct direction.
Why is the compass needle kept in a closed glass vessel Answers for class 6?
The compass needle is kept in a closed glass vessel to prevent any interference from external magnetic fields, which could disrupt its accurate alignment with the Earth's magnetic field. Keeping the needle enclosed helps maintain its sensitivity and stability, ensuring that it always points towards the magnetic north.
What is the box that surrounds around a compass called?
The box that surrounds a compass is called a compass housing or compass casing. It helps protect the compass needle and dial from damage and external interference.
What is an navigational tool with a needle?
A navigational tool with a needle is a compass because it helps you to navigate which is cosidered as a tool. A compass has a needle inside to point which way is north. There is your answer :)
Why should a compass be held flat?
A compass should be held flat to ensure that the magnetic needle can move freely and accurately point towards magnetic north. Holding it flat also helps prevent the needle from sticking or getting caught on surfaces, which could result in inaccurate readings.
What kind of oil is used to fill a compass?
The oil used to fill a compass is typically a type of mineral oil or a synthetic oil. These oils are chosen for their low viscosity and stability over a range of temperatures, which helps ensure that the compass needle moves freely and accurately. The oil also serves to dampen the movement of the needle, allowing for more precise reading by reducing oscillation.
What are the arrows on the compass called?
The arrows on a compass are called "compass needles." They indicate the direction of magnetic north, allowing users to orient themselves. The needle typically has one end marked, often colored red, to signify the north direction. This helps in navigation and determining bearings.
What is the circuit's total resistance?
You take the wire(s) that are in the circuit and place it on on a compass. Hold the compass still and the needle in the compass will move. However far that the needle is turned will detrmine how much resistance is in the circuit. (You know you have done this correctly if the needle in the compass spins counter clockwise.) Hope this helps you out :)
What do the poles of a magnetized needle on a compass align themselves with?
The poles of a magnetized needle on a compass align themselves with the Earth's magnetic field, pointing towards the magnetic north and south poles. This alignment helps the needle to indicate the direction of north.

What technique is used almost exclusively for sighting with a compass?
The technique used almost exclusively for sighting with a compass is called "bearing." This involves aligning the compass needle with the orienting arrow, then sighting an object in the distance through the sighting feature (usually a notch or a lens) of the compass. The angle or direction indicated by the compass can then be used to navigate towards that object. This method ensures accurate direction-finding and helps in orienting maps as well.
How do you use a compass with lens?
To use a compass with a lens, hold the compass level and look through the lens to read the compass direction. The lens helps in magnifying the needle and making it easier to see the direction accurately. Ensure the compass is away from any metal objects or magnetic interference to get an accurate reading.

The compass needle is kept in a closed glass vessel to prevent any interference from external magnetic fields, which could disrupt its accurate alignment with the Earth's magnetic field.
