FAQ

Those who are looking for an answer to the question «Why light is characterized by electric vector although it also possesses the magnetic vector?» often ask the following questions:

👉 How are the electric vector and magnetic vector related?

The velocity of the wave would be the speed of light with a direction component. This is related to the electric and magnetic field vectors as something like: c → = c E B (E → × B →) However, the relationship you are probably looking for relates the magnitudes as: E = c B. Also see:

👉 Are light electric and magnetic?

Instead light is an oscillating electric and magnetic field. If you take an electron and put it in a static electric field (e.g. around a Van de Graaff Generator) then the electron feels a force due to the field and will move.

👉 Does electric field cause changing magnetic field also?

The correct interpretation in the opposite way is that a "changing" electric field produces a magnetic field. Also the change should be with respect to time. An example would be a current carrying wire. A current carrying wire produces a magnetic field around it, given by Biot-Savart's law.

Hence in 1908 Hermann Minkowski said this in Space and Time: “In the description of the field caused by the electron itself, then it will appear that the division of the field into electric and magnetic forces is a relative one with respect to the time-axis assumed; the two forces considered together can most vividly be described by a certain analogy to the force-screw in mechanics; the analogy is, however, imperfect”.

Although vectors are mathematically simple and extremely useful in discussing physics, they were not developed in their modern form until late in the 19th century, when Josiah Willard Gibbs and Oliver Heaviside (of the United States and England, respectively) each applied vector analysis in order to help express the new laws of electromagnetism, proposed by James Clerk Maxwell.

Is the electric force a vector or a vector field?

The electric force is just a vector, not a vector field. The Coulomb force formula you wrote depends on "some" position vectors $\vec r_1,\vec r_2$, much like fields $\Phi(\vec r)$ depend on the position vector $\vec r$, but it's a different kind of a dependence.
