AP EAMCET · PHYSICS · Magnetic Effects of Current
The magnetic field at the centre \(\mathrm{C}\) of the arrangement shown in figure is
- A \(\frac{\mu_0 i}{2 \pi r}(1+\pi)\)
- B \(\frac{\mu_0 i}{4 \pi r}(1+\pi)\)
- C \(\frac{\mu_0 i}{\pi r}(1+\pi)\)
- D \(\frac{\mu_0 i}{r}(1+\pi)\)
Answer & Solution
Correct Answer
(B) \(\frac{\mu_0 i}{4 \pi r}(1+\pi)\)
Step-by-step Solution
Detailed explanation
According to diagram in the question, magnetic field at the centre \(C\) will be sum of the magnetic field due to straight part \(B_1\) and magnetic field due to circular part \(B_2\). \(\because\) From Maxwell's right hand thumb rule direction of both magnetic field at the…
