Consider a loop which is subjected to a magnetic flux variation. Among the points that turn there will be the electromotive force induced?
DaleSpam said:Yes. ##EMF = \int E \cdot dl##
Caio Graco said:The induced electromotive force between that point?
Electromotive force induced, also known as induced voltage, is the creation of an electric potential difference in a conductor due to a changing magnetic field. This can occur through the process of electromagnetic induction.
Electromotive force induced is directly related to Faraday's law of induction, which states that the induced electromotive force in a closed circuit is equal to the rate of change of magnetic flux through the circuit. In other words, the greater the change in magnetic flux, the greater the induced voltage.
The magnitude of electromotive force induced depends on several factors, including the strength of the magnetic field, the speed at which the conductor cuts through the magnetic field, and the angle between the conductor and the magnetic field. Additionally, the number of turns in the conductor and the material of the conductor can also affect the induced voltage.
Electromotive force induced has many practical applications, including generators, transformers, and electric motors. It is also used in devices such as microphones, speakers, and magnetic levitation trains.
Unlike DC, which relies on a constant source of electrical potential difference, and AC, which alternates in direction, electromotive force induced only occurs when there is a changing magnetic field. This means that it is only present for a limited time and is not a continuous source of electrical energy.
