NEET 2016 Physics Inductance MCQ Question
Type: MCQ-numerical-Medium-Class 12
A long solenoid has 1000 turns. When a current of 4 Å flows through it, the magnetic flux linked with each turn of the solenoid is 4 × 10⁻³ Wb. The self-inductance of the solenoid is
A
2 H
B
1 H
C
4 H
D
3 H
Correct Answer
Option B
Detailed Explanation
The self-inductance L is given by L = NΦ/I, where N is the number of turns, Φ is the magnetic flux, and I is the current. Substituting the given values yields L = 2 H.
