Michael Faraday is generally credited with discovering the phenomenon of induction in 1831, although Francesco Zantedeschi's work in 1829 may have foreseen this.

1. The phenomenon of electromagnetic induction was discovered by the British physicist Michael Faraday. The law of electromagnetic induction, also known as Faraday's law of electromagnetic induction, refers to the phenomenon of induced electromotive force due to changes in magnetic flux. The discovery of the phenomenon of electromagnetic induction, the ruler is one of the greatest achievements in the field of electromagnetism.
In the same year, the famous Danish physicist Oster discovered the magnetic effect of electric current, which opened the prelude to the study of the essential connection of electromagnetism, and his major discovery of the number of nuclei soon spread throughout Europe and was confirmed by many physicists. Therefore, it is believed that electric currents are capable of generating magnetic fields.
3. Some physicists before Faraday had already explored the way of generating electricity from magnetism. Between 1821 and 1822, Ampère experimented with induced electric currents, but he failed to discover the phenomenon of electromagnetic induction.
4. From 1821 to 1831, Faraday spent 10 years, from the idea to the experiment, the long years, the pain of failure, the hardships of life, Faraday tasted all kinds of bitterness, after countless repeated research experiments, finally discovered the phenomenon of electromagnetic induction, determined the basic law of electromagnetic induction in 1831, and made a major breakthrough in magnetic induction electricity.

Definition: (Why it happens).
When a part of the conductor of a closed circuit moves to cut the magnetic inductance line in the magnetic field, an electric current is generated in the conductor, which is called electromagnetic induction. Due to magnetic flux.
Change produces the phenomenon of induced electromotive force.
Substance: The essence of the electromagnetic beam strip can be traced back to Maxwell.
Electromagnetic field theory: the changing magnetic field produces a high-generation electric field in the surrounding space, and when the conductor is in this electric field, the free electrons in the conductor move directionally under the action of the electric field force to produce a current, that is, an induced current; If it is not a closed loop, the directional movement of free electrons in the conductor causes the accumulation of positive and negative charges at both ends of the disconnection, resulting in a potential difference.
- Induce electromotive force.
The reason is included.

The discoverer of the phenomenon of electromagnetic induction was Michael Dan Faraday.
Electromagnetic induction, also known as magnetoelectric induction, refers to the phenomenon that a part of the conductor of a closed circuit moves to cut magnetic inductance lines in a magnetic field, and an electric current is generated in the conductor. This phenomenon of using a magnetic field to generate an electric current is called electromagnetic induction, and the resulting current is called induced current.
Michael Faraday, an English physicist, chemist, and a well-known self-taught scientist, was a student and assistant to the famous British chemist David, whose discoveries laid the foundation of electromagnetism and was the forerunner of James Clark Maxwell.
Faraday's invention of the disc generator was the first generator created by man.
Because of his great contributions to electromagnetism, he is known as the "father of electricity" and the "father of alternating current".
The magnetic flux has not changed, and there is no induced current. >>>More
The magnitude and direction of the current in the coil m determine the magnitude and direction of the magnetic field generated by the current, and the alternating current shown in Figure (b) will generate an alternating magnetic field with the same change law when the alternating current shown in Figure (b) is passed through the coil. The alternating magnetic field passes through the coil n, and the current will be induced in the ** coil n. >>>More
When the magnetic flux passing through the loop changes, the magnitude of the induced electromotive force in the loop is proportional to the rate of change of the magnetic flux passing through the loop, i.e., induction = t This is Faraday's law of electromagnetic induction. (2) It shows that when the magnetic flux increases, t>0, then the inductance is negative, that is, the magnetic field generated by the induced current is opposite to the direction of the original magnetic field; When the magnetic flux decreases, t <0, then the inductance is positive, that is, the magnetic field generated by the induced current is in the same direction as the original magnetic field. In secondary school, the magnitude and direction of physical quantities are often discussed separately. >>>More
