A non-Coulomb electric field has characteristics that deviate from the traditional Coulomb's law, which describes the force between charged particles. In a non-Coulomb electric field, the force between charges may not follow a simple inverse square relationship. This can lead to more complex interactions between charged particles, resulting in different effects on the behavior of the charges in the field. These effects can include non-linear force relationships, the presence of magnetic fields, and the generation of electromagnetic waves.

What is the trajectory of a charge in an electric field?
The trajectory of a charge in an electric field is determined by the direction and strength of the electric field. The charge will experience a force in the direction of the electric field, causing it to move along a path determined by the field's characteristics.
How can you experimentally distinguish an electric field from a gravitational field?
Introduce two opposite charged objects one AT A TIME and if they move IN THE SAME DIRECTION, they are in a gravitational field, if they move IN DIFFERENT direction they are in an electric field.
Why is a vibrating electric field an example of an electromagnetic wave?
A vibrating electric field produces a changing magnetic field, which then generates a changing electric field and so on, creating a self-propagating wave. This wave consists of oscillating electric and magnetic fields perpendicular to each other and to the direction of wave propagation, thus exhibiting the characteristics of an electromagnetic wave.
What is electric displacement?
Electric displacement (D) is a concept used in electromagnetism to describe the electric field inside a material. It takes into account the effects of both free and bound charge distributions. It is related to the electric field inside a material through the equation D = εE, where ε is the permittivity of the material and E is the electric field.
What are the three main effects of an electric current?
The main effects of an electric current are the generation of heat (thermal effect), the production of light (light effect), and the creation of a magnetic field (magnetic effect).

Does an electric field get weaker the closer you get to the charge object?
No. The strength of the electric field remains unchanged regardless of your proximity. However, the effects of the electric field on you are more pronounced as you move closer to it.

What happens to the electric field when you get farther from an electric charge?
An electric field gets stronger the closer you get to a charge exerting that field. Distance and field strength are inversely proportional. When distance is increased, field strength decreases. The opposite is true as well. Additionally, field strength varies as the inverse square of the distance between the charge and the observer. Double the distance and you will find that there is 1/22 or 1/4th the electric field strength as there was at the start of your experiment.
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
When an electric field is applied to a conductor does the electric field develops within the conductor or around the conductor?
The electric field will develop inside the conductor, depending on the characteristics of the electric field -- in a steady state (DC) or in an alternating mode (AC). The higher the frequency of oscillation, the shallower the field will reside in the conductor -- skin depth (check the related link). Hence, when the frequency is high, only the few mm's of the outer skin participates in the action (AC electrical conduction.) In steady state (DC), the frequency is zero, the electric field is distributed inside the whole conductor.
What are the basic characteristics of dielectric materials?
Dielectric materials are insulators that can be polarized by an electric field, allowing them to store electrical energy. They exhibit high resistivity and low electrical conductivity, preventing the flow of electric current. Key characteristics include a high dielectric constant, which indicates their ability to store charge, and a breakdown voltage, which signifies the maximum electric field they can withstand without becoming conductive. Additionally, dielectrics have low losses, meaning they dissipate minimal energy as heat when subjected to an alternating electric field.
