Greetings colleagues of the Hive community, welcome back to my blog, where you can find content from the wide universe of science, mathematics, biology, physics, chemistry, philosophy and general knowledge accompanied by scientific popularization, a special greeting to the communities that stimulates the content of science.

Introduction

Continuing the content of science to the level of physics, in reference to the magnetic component in reference reader friend where it exerts the presence of a magnetic field, it is possible to place a load that in turn moves with a speed , it is clear that this load will suffer a deviation in its trajectory, because a force appears on it due to the field where it is located. Also share as was the magnetic effect by a mechanism of selenoid, as it can be any body, matter or device that handles a magnetic field, where evidence that performs or exercises characteristic itself that its intensity is very abundant in its interior and weak on the outside in the form of releasing the magnetic field through this mechanism.

Taking into account also the first Laplace's law, this is based only on the fact that the electric current, this can create magnetic field around it, from the neutral point where it begins to generate force, since thenspin is to the amount of angular motion that electrons can possess.

For the case of the electromagnetic induction reader friend, a very important data thanks to the studies carried out by Faraday in a moment of the history for the year 1831, had the experience of evidencing at the moment of checking, that an electric current can be generated when a magnetic field is modified, where the orientation to the origin of the physical phenomenon of the induction effect, since from magnetic camoi this can produce current.

One of the great discovery from a pole N of the magnet to the spiral, using a mechanism of galvanometer this indicated that a current, which in turn creates a field opposed to the magnet, as also if it moves away the pole S, they occur exactly the same as effect is the most singular, an example of this type of current is evidenced in copper coils of form of spiral and the motors automotive connub induced circuit.

If we join the first Faraday's Law and induction, it shows us that an electric tension is created, which is induced in an electric circuit, the singularity of this, my reader, is proportional to the variation of the magnetic flow that goes through it, because opening or closing a circuit implies that this can cause a variable field, so that the coils would be in rest. In a circuit there is the presence of a flow variation, which generates an electromotive force that induces a primary electric current considering if the circuit is closed.

It is also evident that the action of a moving medium with respect to a magnetic field of non-uniform static form, the magnetic field manages to make possible a variation of the field lines, only when this is that crossed on its surface by a movement of a turn.
