Updated On: Apr 24, 2026
- Eddy current : Induction furnace
- Transformer : Laminated core
- Induced emf : Biot-Savart law
- Ac generator : Electromagnetic induction
- Coaxial coils : Mutual inductance
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Induced emf is governed by Faraday's law and Lenz's law, not Biot-Savart law.
Step 2: Detailed Explanation:
Biot-Savart law gives magnetic field due to a current, not induced emf.
All other pairs are correctly matched.
Step 3: Final Answer:
Mismatched pair: Induced emf : Biot-Savart law.
