Meaning of Magnetic Field

Before entering fully into the meaning of the term magnetic field, it is necessary to proceed to discover the etymological origin of the two words that give it its shape:
-Field comes from Latin, specifically from “campus” and can be translated as “flat terrain”.
-Magnetic, on the other hand, derives from the Greek. More exactly, it comes from the word “magnetikos” which can be translated as “relative to the magnet” and which is the result of the sum of two components of that language: the noun “magnes”, which means “magnet”, and the suffix “-ico “, Which is used to indicate” relative to “.

In the field of physics, the spatial region at whose points a magnitude is defined is called a field. The adjective magnetic, for its part, alludes to what is linked to magnetism: the property that currents of electricity and magnets have to generate rejections and mutual attractions and other actions at a distance.

From these definitions we can advance with the concept of magnetic field. This idea refers to the sector of space on which a magnetic element has an impact. Magnetic field is also said to the magnitude expressed in amps / meters that reflects how strong a magnetic force is.

A point in a magnetic field can be specified from the magnitude and direction of a charge. That is why it is a vector field: the points of the Euclidean space are associated with a vector.

Magnetic fields can be explained from the Lorentz force, which is the force exerted by the field when it receives a current of electricity or a charged particle. The electric charge of value X moves through space at a certain speed and experiences the result of a force that is secant and that is proportional to the field and the speed.

The magnetic field can be generated by a displacement current. In this case, the field varies in time. It can also have its origin in a conducting electric current that, if constant, creates a magnetic field that remains static.

Other interesting facts about the magnetic field are the following:
-According to the International System, the unit of the magnetic field is the Tesla. This is represented by the letter t. 1 Tesla is considered to be the magnetic field that the force of 1 Newton (N) exerts on a charge of 1 Coulomb (C).
-In the same way, we must not forget that another unit used to measure the aspect at hand is the Gauss (G). In this case we can say 1 Tesla is equal to 10,000 Gauss. It is true that this unit is not part of the mentioned International System, but its use is very widespread.
-When analyzing and calculating a magnetic field, it is important to rely on elements such as the creative charge of the field, the distance, the speed of the aforementioned charge, the permeability of free space and even the so-called unit vector.
