A solenoid with 100 turns per metre carries a current of 1.2 A. The magnetic intensity inside the solenoid is :
- A \( 83 \text{ Am}^{-1} \)
- B \( 120 \text{ Am}^{-1} \)
- C \( 150 \text{ Am}^{-1} \)
- D \( 60 \text{ Am}^{-1} \)
Answer & Solution
Correct Answer
(B) \( 120 \text{ Am}^{-1} \)
Step-by-step Solution
Detailed explanation
\( H = nI \) \( H = (100 \text{ turns/m})(1.2 \text{ A}) \) \( H = 120 \text{ Am}^{-1} \)
