What is Lenz’s law? 

Answer:

German physicist Heinrich Lenz deduced a law that determines the direction of the induced current. Lenz's law states that the direction of the induced current always opposes the cause responsible for its production. Michael Faraday discovered electromagnetic induction. Heinrich Lenz says that the induction effect always opposes and would flow in a direction so that it could oppose the flux change. 

What is a transformer?
