Physics Question from JEE Main 2023 · 25 January, Shift 1

A solenoid of 12001200 turns is wound uniformly in a single layer on a glass tube 2 m2 \, \text{m} long and 0.2 m0.2 \, \text{m} in diameter. The magnetic intensity at the center of the solenoid when a current of 2 A2 \, \text{A} flows through it is:

  • A

    2.4×103 A m−12.4 \times 10^3 \, \text{A m}^{-1}

  • B

    1.2×103 A m−11.2 \times 10^3 \, \text{A m}^{-1}

  • C

    1 A m−11 \, \text{A m}^{-1}

  • D

    2.4×10−3 A m−12.4 \times 10^{-3} \, \text{A m}^{-1}
