MCQ
For adjoining fig., The magnetic field at point, $P$ will be
- A$\frac{\mu_0}{4 \pi} \odot$
- B$\frac{\mu_0}{\pi} \otimes$
- C$\frac{\mu_0}{2 \pi} \odot$
- ✓$\frac{\mu_0}{2 \pi} \otimes$
✓
Answer
Correct option: D.
$\frac{\mu_0}{2 \pi} \otimes$
d
Magnetic field due to $5 A \rightarrow \frac{5 \mu_0}{2 \pi \times 2.5}=\frac{2 \mu_0}{2 \pi} \otimes$
Magnetic field due to $5 A \rightarrow \frac{5 \mu_0}{2 \pi \times 2.5}=\frac{2 \mu_0}{2 \pi} \otimes$
Magnetic field due to $2.5 A \rightarrow \frac{2.5 \mu_0}{2 \pi \times 2.5}=\frac{\mu_0}{2 \pi} \odot$
Resultant Magnetic field $B_{net}=\frac{2 \mu_0}{2 \pi}-\frac{\mu_0}{2 \pi}=\frac{\mu_0}{2 \pi} \otimes$
