The terms, 'Magnetic North' and 'Magnetic South', are used to distinguish these locations from 'True North' and 'True South'. It's very important to understand that they do not refer to the magnetic polarity at these locations. Unlike True North and True South, the actual locations of Magnetic North and Magnetic South vary over time.
The ends of a magnet or compass needle are named after the directions in which they point (or, more accurately, the direction of the field along which they align) and, originally, were referred to as their 'North-seeking' and 'South-seeking' poles. The terms 'seeking' are now considered archaic and are no longer used, but the remaining terms 'north' and 'south', by convention, also define their magnetic polarities.
In accordance with the law that 'like poles repel while unlike poles attract', this means that the magnetic polarity of 'Magnetic North' is actually a south, while the magnetic polarity of 'Magnetic South' is a north. In other words, the earth behaves as though there was a giant bar magnet, buried deep within its crust, whose south pole is located in the Northern Hemisphere and whose north pole is located in the Southern Hemisphere.
Any answers that suggest that the 'North-seeking' pole of a compass is really a 'south' pole is completely incorrect and indicates a lack of understanding of the behaviour of magnets.
Additional Comment[On modern maps, the north is at the top of the map. This was not always so, and in early times, the east was at the top. For sunrise was a reliable indicator. Hence the term 'to orient your map'. From the Latin oriens, literally rising. Similar conventions occur in several languages. And the Latin for Occident means 'setting'.]
The force of friction ALWAYS acts in the direction exactly opposite to the directionin which the object is moving.If the friction force acted in the same direction as the object's motion, then youwould want to have as much friction as possible, because that would help youmove the object with less fuel.
No, they are always in the same direction, as expressed in Newton's Second Law, which is usually expressed as: F=ma (force = mass x acceleration). In this equation, acceleration is a vector, so when multiplying it by a mass (which is NOT a vector), you get another vector that points in the same direction.
The zenith is the direction directly above the observer. The astronomical horizon is the plane that is perpendicular to that direction, i.e. horizontal. The "true horizon", however, is the cone from the observer to the point on the earth, below which you can not "see over", so it is a small amount lower in angle. In practice, the two horizons can be considered to be the same, because the height of the observer is often small in comparision to the diameter of the earth, unless the observer is standing on a tall point, such as a mountain.
There is no net force OF the object. If the forces act in the same direction, the net force is magnitude of the net force is the sum of the forces and acts in the same direction. If the forces act in opposite directions, the magnitude of the net force will be the difference between their magnitudes and it will act in the direction of the larger of the two forces.
If two vectors, acting simultaneously at a point, can be represented both in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point, then the resultant is represented completely, both in magnitude and direction by the diagonal of the parallelogram passing through the point.

A freely suspended magnet will always point in the same direction because it aligns itself with the Earth's magnetic field. This causes one end of the magnet to point towards the Earth's magnetic north pole and the other end to point towards the South pole.
When there is a large current in the direction shown, each compass point will point in the same direction as the current.
yes it rotates on an axis and 'always' in the same direction.
No it does not. Since the Earth is constantly spinning, and also rotating around the sun, the earth will point in all 360 degrees.
A compass needle can be trusted to always point in the same direction- the North (magnetic) Pole. It refers to someone that can always be trusted to do the same thing every time.
A compass points towards magnetic north, which is the direction that a magnetic needle aligns itself with the Earth's magnetic field. This is not the same as true north, which is the geographic North Pole. The difference between magnetic north and true north is known as magnetic declination and varies by location.
No, when velocity decreases and acceleration arrows point in the same direction, it means the object is speeding up in the negative direction.
A polygon has no direction so the phrase "in the same direction" makes no sense. Consequently, the question has no meaning.
Dew point is not always the same. It changes throughout the course of the day.
Dew point is not always the same. It changes throughout the course of the day.
Yes. f=ma the direction of acceleration is the direction of the force and vice versa.
