Concept

Problem: In the questions below there are 6 induction processes. The circle with the dot denotes a magnetic field pointing out of and the circle with the x denotes a magnetic field pointing into the screen. A line represents a conductor, while a bar denotes a sliding conductor. An arrow labeled "v" indicates the direction in which the conductor or sliding conductor is moving. Use Lenz's law to determine which of induced currents have a counterclockwise direction. Choose all that apply.

Lenz's law states that when an emf is generated by a change in the magnetic flux, according to Faraday's law, the polarity of the induced emf produces a current whose magnetic field is opposing the change that produced it. 

Faraday's law mentioned, states that any change in the magnetic surrounding or a coil of wire causes an emf to be induced in the coil.
