Electric charge

In the field of physics, electric charge is a property of matter that is responsible for producing electrostatic interactions. Matter is made up of atoms that in turn are made up of electrons that have a negative electrical charge and protons that have a positive electrical charge . The protons are in the nucleus of the atom and the electrons in the crust revolving around the nucleus. … Read more

Coriolis effect

In the field of physics and meteorology, the study of the Coriolis effect is very important to better understand what are the forces that intervene in the rotation of the Earth and what effect they produce depending on its location on the planet. What is the Coriolis effect? The Coriolis effect is a force that is generated due to … Read more

Gravitational waves

In the field of physics, scientist Albert Einstein predicted the existence of gravitational waves , which could only be discovered a hundred years after their prediction by LIGO scientists in 2015 . These represent an important advance in Einstein’s theory of relativity and for science in general.   What are gravitational waves? Gravitational waves represent a disturbance of space-time generated by an … Read more

Faraday cage

When an electrical charge accumulates on the outside of a metal box, the electrons in the metal that make it up move to cancel out any charge on the inside. This is precisely what Michael Faraday discovered with the Faraday  cage , that an electrical charge cannot be passed into a metal box or covered with an electrical mesh … Read more

Lenz’s Law

The law of Lenz , also called Lenz-Faraday law, is used in the field of electromagnetism and to determine the direction of the induced current. It can be stated as follows: a change in the state of an electromagnetic system causes a phenomenon whose effects tend to oppose this change. Heinrich Friedrich Lenz, a physicist of German origin, proposed in 1834 … Read more

Faraday’s Law

In the area of ​​physics, Faraday’s law allows the macroscopic phenomena of electromagnetic induction to be established. This law investigates the study of magnetic fields, electromagnetism and electrochemistry. Based on the works of Michael Faraday in 1831 , it is a law of moderation, which means that it describes effects that are opposed to their causes. Thanks to it, a set … Read more

Electromotive force

The electromotive force (EMF) is the energy originated from any medium, channel or device that provides an electric current , being all energy capable of providing or serving to supply a viable electric current, which can be used by a device without require moving parts, such as portable cells or batteries. What is the electromotive force? The electromotive … Read more

Planck’s constant

The Planck constant is one of the fundamental constants of physics proposed by Max Planck in 1900 to explain the radiation of a black body . The radiated energy cannot take any kind of values ​​but only multiple integer values ​​of a quantum of energy. Planck’s constant links the value of energy to the frequency of radiation: E = hf . Planck’s work marked … Read more

Magnetic induction

Today, it is difficult to imagine a world without generators and without electric motors. This is a contribution that we owe to the researcher Michael Faraday, who discovered magnetic induction , as well as to contemporary scientists of his time. Magnetic induction refers to the process in which a time-varying magnetic field produces an electric field . This phenomenon has various applications … Read more

Electric field

The electric field is any spatial area where the electric charges , which can be positive or negative, are related in a certain space limit, the electric field being both the delimitation of the space in the plane, as well as the space of a body charged with electricity. . It is not measurable in itself, but what is measured is the … Read more
