Purpose & Scientific Principle
The aim is to let the audience understand the different strengths of magnetic fields formed by different energized coils through interaction, so as to understand the content of Lenz's law.
How to Operate
After summarizing Ampere's electrodynamics and Faraday's electromagnetic induction phenomenon, Lenz proposed in 1833 that the induced electromotive force prevents the movement of the magnet or coil that generates electromagnetic induction, which is called Lenz's law.
Lenz's law is the specific embodiment of the law of conservation of energy in the phenomenon of electromagnetic induction. Lenz's law can also be expressed as: the effect of induced current always opposes the cause of induced current, that is, the magnetic field of induced current always hinders the change of magnetic flux that causes induced current. Simply put, it is the law of "come and refuse to stay". This is the main content of Lenz's law.
The effect of induced current always opposes the cause of induced current, that is, the magnetic field of induced current always resists the change of magnetic flux that causes induced current.
