Electric field lines are drawn with arrows to show the direction of the force that a positive test charge would experience if placed in the field. The direction of the electric field at any point is the direction that a positive test charge would move when placed in the field at that point.
Any point from the Earth's North Pole would be in the south direction without any deviation.
To determine the direction of the magnetic field at any point, you can use the right-hand rule. Point your thumb in the direction of the current flow, and your fingers will curl in the direction of the magnetic field.
No. the zero vector has no direction, therefore it has no significance.
To turn on a fixed point in any direction desired.
The direction of an object moving along a circular path is constantly changing. At any given point, the direction of the object is tangent to the circle at that point.
from anywhere on a map south is the direction towards the south pole.
That simply means that the charge doesn't "point" to any particular direction in space. While you can talk about a force of 100N in the upwards direction, it doesn't make sense to talk about a charge of 0.1C to the left - there simply is a charge, it doesn't point in any direction.
A force can be applied to an object at any point on its surface or through a specific contact point. The direction of the force determines how the object will move or behave in response to the applied force.
The south Pole is most southern point on the earth. If you stand there, then any direction you can face is north.
Yes, that is correct. The direction of the electric field at any point represents the direction in which a positive test charge placed at that point would experience a force. If a negative test charge is used, the force it experiences would be in the opposite direction of the electric field.
