Heinrich Friedrich Emil Lenz was a Russian physicist known for his contributions to electromagnetism. He formulated Lenz's law, which states that an induced electric current flows in a direction that opposes the change that caused it. This principle is crucial in understanding electromagnetic induction and is represented by the negative sign in Faraday's law of induction. Lenz's law ensures the conservation of energy by demonstrating that work must be done to induce a current, which then manifests as heat due to resistance. His work was foundational in the field of physics.12
