JEE AdvancedPhysicsMagnetismMCQ+3 / −1
Which one of the following options represents the magnetic field B⃗\vec{B}B at O\mathrm{O}O due to the current flowing in the given wire segments lying on the xyx yxy plane? JEE Advanced 2022 Paper 2 Online Physics - Magnetism Question 11 English
  1. A
    B⃗=−μoIL(32+142π)k^\vec{B}=\frac{-\mu_{o} I}{L}\left(\frac{3}{2}+\frac{1}{4 \sqrt{2} \pi}\right) \hat{k}B=L−μo​I​(23​+42​π1​)k^
  2. B
    B⃗=−μoIL(32+122π)k^\vec{B}=-\frac{\mu_{o} I}{L}\left(\frac{3}{2}+\frac{1}{2 \sqrt{2} \pi}\right) \hat{k}B=−Lμo​I​(23​+22​π1​)k^
  3. C
    B⃗=−μoIL(1+142π)k^\vec{B}=\frac{-\mu_{o} I}{L}\left(1+\frac{1}{4 \sqrt{2} \pi}\right) \hat{k}B=L−μo​I​(1+42​π1​)k^
  4. D
    B⃗=−μoIL(1+14π)k^\vec{B}=\frac{-\mu_{o} I}{L}\left(1+\frac{1}{4 \pi}\right) \hat{k}B=L−μo​I​(1+4π1​)k^
