An electric field sometimes E-field [1] is the physical field that surrounds each electric charge and exerts force on all other charges in the field, either attracting or repelling them. Electric fields and magnetic fields are both manifestations of the electromagnetic force , one of the four fundamental forces or interactions of nature.

Definition: The region around the electric charge in which the stress or electric force act is called an electric field or electrostatic field. If the magnitude of charge is large, then it may create a huge stress around the region. The electric field is represented by the symbol E. The SI unit of the electric field is newton per coulomb which is equal to volts per meter.

Electric field , an electric property associated with each point in space when charge is present in any form. The magnitude and direction of the electric field are expressed by the value of E , called electric field strength or electric field intensity or simply the electric field. Knowledge of the value of the electric field at a point, without any specific knowledge of what produced the field, is all that is needed to determine what will happen to electric charges close to that particular point. Instead of considering the electric force as a direct interaction of two electric charges at a distance from each other, one charge is considered the source of an electric field that extends outward into the surrounding space, and the force exerted on a second charge in this space is considered as a direct interaction between the electric field and the second charge. If the second, or test, charge is twice as great, the resultant force is doubled; but their quotient, the measure of the electric field E , remains the same at any given point. The strength of the electric field depends on the source charge, not on the test charge. Strictly speaking, the introduction of a small test charge, which itself has an electric field, slightly modifies the existing field.

Physics of the Life Sciences pp Cite as. In this chapter we begin our study of electromagnetism, one of the four fundamental interactions in nature. Aside from gravity, ultimately all of the forces that we are familiar with are due to electromagnetic interactions; pushes and pulls, normal, frictional, tension, compression, shear, and viscous forces are all electromagnetic in origin. Other forces that we learn about are also electromagnetic, including the historically diverse electric and magnetic forces as well as all the various chemical bonding forces. In fact, all of chemistry other than nuclear chemistry is basically electromagnetic in origin. Even more surprising is that light and other forms of nonnuclear radiation are electromagnetic in nature and can exert electromagnetic forces.

Neutral atoms can be made to behave like charged particles by 'synthetic' electric and magnetic fields. These are created through the production of a synthetic gauge field in a state of matter known as a Bose—Einstein condensate BEC , in which the atoms are all identical and behave collectively as if they were one 'superatom'.

In general, we classify materials according to their electrical properties into three types: 1 Conductors. Because of this collapsing magnetic field, current will be induced in the secondary winding. Light waves travel with a velocity of,3. Whenever a signal is driven along a wire, a magnetic field develops around the wire. The phase contrast microscopy is based on the principle that small phase changes in the light rays, induced by differences in the thickness and refractive index of the different parts of an object, can be transformed into differences in brightness or light intensity. As for the electric field, a conductor is a material with electrons that can move easily in response to electric fields and their tendency is to shield out the electric field to obtain force balance.

    An Example: Calculate the magnitude of electric force between a electron and a proton at a distance of r= x 10 m.
