coulombfältet

Coulombfältet, also known as the electrostatic field, describes the influence that an electric charge has on the space around it. This influence is what causes other electric charges to experience a force. The field is a vector quantity, meaning it has both magnitude and direction at every point in space. The magnitude of the Coulomb field at a specific point is proportional to the magnitude of the source charge creating the field and inversely proportional to the square of the distance from the source charge. This relationship is quantified by Coulomb's Law. The direction of the field is radially outward from a positive source charge and radially inward towards a negative source charge.

The Coulomb field is a fundamental concept in electromagnetism, providing a way to understand the interactions between stationary electric charges without direct contact. It is often visualized using electric field lines, which are drawn to indicate the direction and relative strength of the field. Field lines originate from positive charges and terminate on negative charges, and their density is proportional to the field's magnitude. The principle of superposition applies to Coulomb fields, meaning that if multiple charges are present, the total field at any point is the vector sum of the fields produced by each individual charge. This concept is crucial for analyzing complex electrostatic systems.
