types of force fields

In our daily life we come across many kinds of mechanical forces such as pull, push, squeeze, stretch etc. Pictures shown below explain the action of some of the above forces...

The lines of force or field lines 1) start from positive charges and end at negative charges. In the case of a single charge, they may start or end at infinity. 2) two field lines can never intersect each other. 3) contract longitudinally. 4) exert lateral pressure on..

Magnetic Field - Magnetic field is a region near a magnetised body where magnetic forces can be detected. In a magnetic field, the magnetic dipole (Two equal and oppositely magnetised poles separated by a distance is referred to as magnetic dipole) experience..

If a small compass needle is placed at a point near the north pole of a bar magnet, the needle turns round on its pivot and settles in a fixed direction as shown in figure. At other points away from the pole the needle settles tangent to the field lines shown. The magnet exerts a magnetic..

Gravitational Field - The space around a body within which its gravitational force of attraction is experienced, is called its gravitational field..

The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that poin..

Electric Field - The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that point. If is the electrostatic force experienced by a test charge q at a point, then the electric fi..
