Close your eyes and think: in an adventure movie scene, our hero holds a glowing compass in his hand. That compass always points in the same direction no matter when you look at it.
How come this vehicle, which was used centuries ago as a tool of discovery, points in the same direction? to find the ‘right path’ Can you provide?
Actually this is completely with the working logic of the compass relevant!
The functioning of the compass is related to the Earth’s magnetic field.
Earth’s magnetic field, magnetic north and magnetic south poles It is defined as a large magnetic field between The compass is a tool that works under the influence of this magnetic field.
magnetic needle, Earth’s magnetic field It aligns towards magnetic north due to its effect. The compass is oriented according to the direction of the magnetic field, which remains constant. The direction of the magnetic field remains largely constant, and so the magnetic needle of the compass generally moves in the same direction.
There is something we should not forget…
The Earth’s magnetic field can change over time and its magnetic poles can even switch places. In this case naturally magnetic needle of the compass will also change direction.
Of course this is still make the compass point in the right direction cannot prevent it.
Well, Compass always points in the same direction On its basis, the effect of the Earth’s magnetic field, which remains constant, is so high!
