Question

The end of compass needle which points towards north is called
A. South pole
B. North pole
C. Geometrical north pole
D. Geometrical south pole

Answer 1

Hint:A compass is a tool that displays the cardinal directions and is used for navigation and geographic orientation. It usually consists of a magnetised needle or other pivotable device, such as a compass card or compass rose, that can align itself with magnetic north.

Complete answer:
The magnetic compass is the most common type of compass. Because the magnetised needle at its heart aligns itself with the horizontal component of the Earth's magnetic field, it serves as a pointer to "magnetic north," the local magnetic meridian.

The needle is torqued by the magnetic field, which pulls the needle's north end or pole toward the Earth's North magnetic pole and the other toward the Earth's South magnetic pole.Hence, a tiny magnet serves as a compass needle. It has a north pole on one end and a south pole on the other.

So, the correct option is B.

Additional information: There are other ways to find north than using magnetism, and there are a total of seven viable options from a navigational standpoint (where magnetism is one of the seven). The gyrocompass and GPS-compass, which use two of the remaining six principles, are commonly referred to as compasses.

Note:At moderate latitudes, the magnetic compass is very dependable, but it becomes worthless in geographic locations near the Earth's magnetic poles. The magnetic declination, or the difference between the direction to geographical north and magnetic north, increases as the compass is pushed closer to one of the magnetic poles. The compass will begin to drift near the magnetic pole and will no longer indicate any particular direction. Due to the so-called magnetic inclination, the needle also starts to point up or down as it gets closer to the poles. Because of this, cheap compasses with bad bearings may become stuck and indicate the wrong direction.
