A compass is a simple device which consists of a small, lightweight magnet which is balanced on a nearly frictionless pivot point. A compass will always point towards the North Pole because of the Earthâ??s magnetic field because the magnet inside the compass is drawn to that magnetic field.

What is true about all compasses?
They all have a hand pointing in a direction.
What direction does a compass needle point when close to north pole?
At either of the magnetic poles, the lines of force enter the planet, so the compass needle will attempt to point straight downward. Due to minor fluctuations, some compasses will spin or pivot about.Near either geographic pole, compasses will still point toward the magnetic pole, which may be north, south, east, or west of the user's position.
When a compass pointing north will point in a different direction when placed near a piece of metal Which causes this to happen?
The needle in compasses is magnetic and is drawn to the Earth's magneticism in the North. When the needle is placed near a metal, as all magnets are, attracted to metals.
Where can one find more information about brass compasses?
There are a number of online websites where one can find information about brass compasses. Stanley London has an excellent selection of brass compasses for sale. Trade Mark London does repairs, maintenance and servicing for antique compasses. The Boreal Arrow has a wide selection of antique and vintage compasses available for purchase and provides some background history for each item.
Why are iron needles good in compasses?
Iron needles are good for compasses because it is thin, and light
What direction do compasses point in the southern hemisphere?
North
What property do compasses use?
They use the fact that the earth acts as a giant magnet so that compasses point towards the north pole.
You are so simple that you can only point yet you guide men all over the world?
A compass. Of course, compasses guide women, too.
Why do magnet compasses not point exactly north?
because of the earth's magnetic core
Compasses always point toward geographic south?
No. If you are talking about magnetic compasses, they are aligned with the Earth's magnetic field, which is not exactly north-south (depending where on the Earth you are located). There are, however, special compasses that make use of the Earth's rotation; those will point north-south, regardless of the magnetic field.No. If you are talking about magnetic compasses, they are aligned with the Earth's magnetic field, which is not exactly north-south (depending where on the Earth you are located).

How do you construct angle 135 degrees?
Note that 135 = 90 + 45.So first construct a right angle, and then bisect the "back" half of it:Draw (horizontal) straight line XABConstruct the perpendicular bisector at A: With the point of your compasses on A draw arcs either side of it on line segments AX and AB.Open your compasses wider, with the point on where the arc in step 2.1 cuts (intersects) AB, draw an arc above the line XAB.With the compasses set the same, with the point on where the arc in step 2.1 cuts AX, draw an arc to cut the arc drawn in step 2.Mark the point where the arcs cut as Y.Draw in line AY.Bisect angle XAY: With the point of the compasses on A, draw arcs on lines AX and AYWith the point of the compasses on where the arc drawn in step 3.1 cuts AX, draw an arc between AX and AY.With the compasses set the same, with the point on where the arc in step 3.1 cuts AY, draw an arc to cut the arc drawn in step 2.Mark the point where the arcs cut C.Draw in line ACAngle CAB is 135oIn drawing the arcs to cut, if they don't cut you may have to either increase the distance between the point and "pencil" of your compasses and/or redraw the arcs longer.
How many types of compasses are there?
There are two main types: Magnetic compasses and gyro compasses.
Are compasses included as technology?
Of course they are. At this point they are not considered cutting edge, but they are most definitely a kind of technology.
