A current through a horizontal power line flows in the east to west direction. The direction of the magnetic field at a point directly below it is from____.

Hint:To answer this question, we first need to understand what is current. A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or space is known as an electric current. The net rate of flow of electric charge through a surface or into a control container is monitored.

Complete answer:
Magnetic field: The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. In a magnetic field, a moving charge experiences a force that is perpendicular to both its own velocity and the magnetic field.

The magnetic field of a permanent magnet attracts or repels other magnets, as well as ferromagnetic elements like iron. Furthermore, a varying magnetic field exerts a force on a variety of non-magnetic materials by changing the mobility of their outer atomic electrons.

Electric currents, such as those employed in electromagnets, and electric fields that fluctuate in time create magnetic fields that surround magnetized things. Because the strength and direction of a magnetic field can vary depending on location, they are characterized as a map that assigns a vector to each point of space, or, more specifically, as a field of pseudovectors (due to the way the magnetic field evolves under mirror reflection).

So, we conclude that the wind is blowing from east to west. The direction of the magnetic field at a position below the wire is north to south, according to the right-hand thumb rule.The magnetic field is directed from south to north at a location exactly above the wire.

So, the final answer is the current flowing via a horizontal power line goes from east to west. The magnetic field at a point exactly beneath it is directed from south to north.

Note: A physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them, is referred to as an electric field. It can also refer to a system of charged particles' physical field.
