• A. Gauss's Law.
• B. Ampère's Law.
• C. Faraday's Law of Induction.
• D. Coulomb's Law.

Hint:

Faraday's Law of Induction is central to many devices, including electric generators and transformers. It describes how a change in magnetic flux can generate an electromotive force (EMF).

Answer 1

The Correct Option is C

Step 1: Understanding the formula.
The given formula \(\varepsilon = \frac{\Delta \Phi}{\Delta t}\) represents the relationship between the induced electromotive force (\(\varepsilon\)) and the rate of change of magnetic flux (\(\Phi\)) over time (\(\Delta t\)). Step 2: Identifying the law.
This relation is a direct representation of Faraday's Law of Induction, which states that the induced electromotive force in a closed loop is proportional to the rate of change of magnetic flux through the loop. Step 3: Conclusion.
Faraday’s Law is one of the fundamental laws of electromagnetism and is crucial for understanding how electric currents can be induced by changing magnetic fields.
