    Q1. A solenoid with 500 turns per meter carries a current of 3 A. What is the magnetic field inside the solenoid?

    • A) 1.88 mT
    • B) 1.2 mT
    • C) 0.6 mT
    • D) 3.14 mT

    Answer: 1.88 mT

    Explanation: B = μ₀nI = 4π x 10⁻⁷ x 500 x 3 = 1.88 mT. Option D is wrong due to incorrect μ₀ value.
