Magnetic Field Strength Formula - Definition, Equations.
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.To calculate the electric-field strength at a certain location, we will only consider the electric-field strength (E.sub.dom) caused by the most dominant source (i.e., the source causing the highest electric-field value at that location), in order to speed up the calculations.An electric field (sometimes abbreviated as E-field) surrounds an electric charge, and exerts force on other charges in the field, attracting or repelling them. Electric fields are created by electric charges, or by time-varying magnetic fields.Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces (or interactions) of nature.
Assuming that in the ground voltage (E.sub.e) x (l.sub.e) is applied to the shortest gap of length (l.sub.e), where (E.sub.e) is the electric field strength permitted in the ground, we write this condition as.Electric field strength definition, electric intensity. See more.
Like charges exert repulsive forces on one another and opposite charges attract. In order to examine this, it is best to use the concept of the electric field. The force of a charged particle in an electric field is the product of the field strength and the amount of charge the particle contains.
