Physics Question from JEE Main 2023 · 1 February, Shift 1

Find the magnetic field at the point PP in the figure. The curved portion is a semicircle connected to two long straight wires.

Figure showing a semicircular curved wire connected to a long horizontal wire at the top and a long vertical wire downward, with current $$I$$ marked and point $$P$$ near the center.Duplicate overlay of the same wire figure showing the semicircular arc, two straight wires, current direction $$I$$, and point $$P$$ inside the semicircle.
  • A

    μ0I2r(1+2π)\frac{\mu_0 I}{2r} \left( 1 + \frac{2}{\pi} \right)

  • B

    μ0I2r(1+1π)\frac{\mu_0 I}{2r} \left( 1 + \frac{1}{\pi} \right)

  • C

    μ0I2r(12+12π)\frac{\mu_0 I}{2r} \left( \frac{1}{2} + \frac{1}{2\pi} \right)

  • D

    μ0I2r(12+1π)\frac{\mu_0 I}{2r} \left( \frac{1}{2} + \frac{1}{\pi} \right)
