STANDARD Physics Faraday's Law MCQ Question
Type: MCQ-numerical-Medium-Class 12
In a coil of resistance 10 Ω, the induced current developed by changing magnetic flux through it, is shown in figure as a function of time. The magnitude of change in flux through the coil in Weber is:
A
8
B
2
C
6
D
4
Correct Answer
Option B
Detailed Explanation
The area under the current-time graph represents the change in magnetic flux. The area of the triangle is 0.5 × base × height = 0.5 × 4 × 0.1 = 0.2. Multiplying by resistance gives the change in flux: 0.2 × 10 = 2 Wb.
