Describe what is electromagnetic induction.Apibūdinti elektromagnetinės indukcijos reiškinį. Explain and use Lenz‘s law.Paaiškinti ir taikyti Lenco taisyklę.

Experiment: Let‘s connect a coil to galvanometer. Let‘s move a magnet into the coil and out of it. What happens? What does the galvanometer show?What happens if we do the opposite?Bandymas : Prie galvanometro gnybtų prijunkime ritę. Į ritę įkiškime magnetą ir jį ištraukime. Kas vyksta? Ką rodo galvanometras? O jeigu bandymą atliksime atvirkščiai?

Induced electric current always flows in such direction, that the magnetic field it creates is opposing the reason that created the current.Or  If the magnetic field containing the closed conductor increases, the induced current excites the magnetic field in the opposite direction. If it weakens the induced current excites the magnetic field in the same direction.

If a magnet moving through a copper ring induced a current in the direction shown, determine the direction in which he magnet was moved.Jeigu judinant magnetą per žiedą, jame indukavosi elektros srovė rodyklės nurodyta kryptimi. Nustatykite, kuria kryptimi juda magnetas.
