Lenz's Law, Faraday's Law, and transformers are foundational concepts in electromagnetism. Faraday's Law states that a changing magnetic field induces an electromotive force (EMF) in a conductor. Lenz's Law extends this, stating the induced EMF opposes the change causing it. Transformers, based on these laws, transfer electrical energy between circuits through electromagnetic induction, efficiently altering voltage levels in power systems, making them crucial in electrical distribution and u...
