Question

Who invented the principle to find the direction of self-induced emf?​

Answer 1

Heinrich Friedrich Emil Lenz.

Lenz's law, in electromagnetism, statement that an induced electric current flows in a direction such that the current opposes the change that induced it. This law was deduced in 1834 by the Russian physicist Heinrich Friedrich Emil Lenz (1804–65).

Answer 2

Answer:

Lenz (later Faraday).

Explanation:

Lenz's law describes the direction of the induced field. Faraday's law was later generalized to become the Maxwell–Faraday equation, one of the four Maxwell equations in his theory of electromagnetism.
