What Is a Vector Field?

A vector field is a function of one vector corresponding to another vector. Vector fields are widely used in physics, especially electromagnetic fields.

The amount of the formed field is a vector, which is called a vector field.

Under a certain unit system, a physical quantity that is sufficient to be represented by a real number is a scalar quantity, such as time, mass, and temperature; here, a real number represents the size of these physical quantities. Unlike a scalar, a vector is a physical quantity, such as speed, force, and electric field strength, in addition to its size. The strict definition of a vector is based on a coordinate system.

Use three-dimensional spherical coordinates. in case

In a certain area of space, except for individual points, if a certain quantity f (P) is defined for each point P in the area, the area is called a field of quantity f (P). The mathematical study of the structure and properties of a field is called

[scalar field]

The amount of the formed field is only a quantity, which is called a scalar field.
