MCQ
Magnetic field at point $'M'$ of given current distribution
- A$\frac{{2{\mu _0}}}{\pi } \odot $
- B$\frac{{5{\mu _0}}}{{2\pi }} \otimes $
- ✓$\frac{{2{\mu _0}}}{{\pi }} \otimes $
- D$\frac{{{\mu _0}}}{{2\pi }} \otimes $
✓
Answer
Correct option: C.
$\frac{{2{\mu _0}}}{{\pi }} \otimes $
c
$\overrightarrow{\mathrm{B}}$ at $\mathrm{M}=\frac{\mu_{0} \cdot 9}{2 \pi \cdot 2} \otimes+\frac{\mu_{0} 3}{26} \otimes$
$\overrightarrow{\mathrm{B}}$ at $\mathrm{M}=\frac{\mu_{0} \cdot 9}{2 \pi \cdot 2} \otimes+\frac{\mu_{0} 3}{26} \otimes$
$=\frac{\mu_{0}}{2 \pi} .4 \otimes=\frac{2 \mu_{0}}{\pi} \otimes$
