What is Field ?
Lets understand the term “Field” first…
A field is a variation of physical state or matter in a certain region of space,
essentially generated by some kind of source.
Let’s understand the definition through examples….

Thus, Fields are two types, i.e.,
1. Scalar Field
2. Vector Field
Definition of Scalar Field :-
A region of space contains a scalar field if it is possible to define a number (either
real or complex) that expresses a physical quantity in every point of space at every
instant of time.
For these fields it is useful to define the equipotential surface, as the surfaces in which
the field f (x, y, z) has constant value.
