Lengci summed up the law of judging the direction of induced current.

Character introduction:

1804 (Jiazi Year) was born in Estonia on February 24th, and 1830 was elected as an academician of St. Petersburg Institute of Communication, and 1834 was elected as an academician.

Lengci's main achievement in physics is the discovery of Lenz's law of electromagnetic induction and Joule-Lenz's law of electrothermal effect.

Introduction:

Lenz's law: the induced current has such a direction that the magnetic field of the induced current always hinders the change of the magnetic flux that causes the induced current.

Lenz's law can also be expressed as: the role of induced current is always the reason to resist induced current.

Lenz's law formula: E = vBL (v is the speed of a rod moving in a magnetic field)

Lenz's law is a law of electromagnetism, which can be used to judge the direction of electromotive force produced by electromagnetic induction.
