I am a bit confused about these two laws as they look the same for me. I have checked the definition at Wikipedia but it always give me more questions than answers.

so here is how I understand it, say in a single phase transformer.

Faraday's law:

The changing voltage (AC) produces a changing magnetic field density at primary, and a voltage is induced on the secondary.

Lenz's Law:

The induced voltage produces a current which tries to keep the original current constant, hence the an inductance in the primary coil.

correct me if I am wrong.
