- Field (mathematics) In mathematics, a field is a set on which are defined addition, subtraction, multiplication, and division, which behave as they do when applied to rational and real numbers. A field is thus a fundamental algebraic structure, which is widely used in algebra, number theory and many other areas of mathematics. The best known fields are the field of rational numbers and the field of real numbers. The field of complex numbers is also widely used, not only in mathematics, but also in many areas of science and engineering.

force field Region around a body in which it experiences an effect (force) due to the presence of another body. See also electromagnetic field. I could not penetrate the force field and I kept getting an electric shock every time I tried to enter it.

magnetic field magnetic field. The definition of a magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge. An example of a magnetic field is the Earth's magnetic field.

Gravitational field In physics, a gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body. Thus, a gravitational field is used to explain gravitational phenomena, and is measured in newtons per kilogram (N/kg). In its original concept, gravity was a force between point masses.

- Depth of Field: One of the most important elements in photography. Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. A preferred selection Depth of field (DOF) in a focused subject in an image can be quite subjective.

What are electromagnetic fields? Electric fields. 1  Electric fields arise from voltage. 2  Their strength is measured in Volts per metre (V/m) 3  An electric field can be present even when a device is switched off. 4  Field strength decreases with distance from the source. 5  Most building materials shield electric fields to some extent.

Field line Field lines depicting the electric field created by a positive charge (left), negative charge (center), and uncharged object (right). The figure at left shows the electric field lines of two equal positive charges. The figure at right shows the electric field lines of a dipole. A field line is a locus that is defined by a vector field and a starting location within the field.

- An electric field is the region surrounding a charged particle, Q, where another charged particle with experience either a force of attraction or repulsion. For point charges, the electric field lines are radial, getting ever farther apart as you get farther from the point charge itself.

Newton's Law of Gravity The gravitational field is defined as the force of gravity at a given point divided by the mass of an object at that point, as depicted to the right.You'll notice that here both g and Fg have arrows above them, denoting their vector nature. The source mass M is now capitalized.he gravitational field is defined as the force of gravity at a given point divided by the mass of an object at that point, as depicted to the right.
