Concept of Fields

We define a field as a region of space under the influence of some physical agency such as gravitation, magnetism and electricity.

Force fields are forces whose sources do not require contact with the body to which they are applied. We identify such force fields as gravitational force, electric force, magnetic force and electromagnetic force.

There are two classes of force fields-scalar fields and vector fields. A scalar field is the one that has only magnitude but no direction, e.g. temperature, energy and density. A vector field is a field that has both magnitude and.... View More
