Fields an forces
Magnetic field
Magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials.
-
-
The magnetic force is a consequence of the electromagnetic force and is caused by the motion of charges.
Two objects containing charge with the same direction of motion have a magnetic attraction force between them.
-
Electric fields
An electric field surrounds an electric charge, and exerts force on other charges in the field, attracting or repelling them.
Electric fields are produced around objects that have electrical charge, or by magnetic field that changes with time.
Electric field strength is a quantitative expression of the intensity of an electric field at a particular location.
Any electrically charged object produces an electric field, This field has an effect on other charged objects in the vicinity.
The field strength at a particular distance from an object is directly proportional to the electric charge on that object.
-
Gravitational field
Gravitational field is a field induced by any object with mass, which will interact with other massive objects by applying a force on it.
This means that any massive object present in another's gravitational field will accelerate towards it, and vice versa.
Forces
Forces (electric, magnetic, gravitational) are fields that extend through space, act at a distance, and can be mapped by their effect on a test object.
