A uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius RR The magnetic field BB produced at perpendicular distance dd from the axis of the cylinder is plotied in a graph. Which of the following figures looks like the plot?A uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field BA uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field BA uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field BA uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field BA uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field BA uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field B

Options

  1. AA magnetic field B=B_0 j exists in the region a
  2. BA magnetic field B=B_0 j exists in the region a
  3. CA magnetic field B=B_0 j exists in the region a
  4. DA magnetic field B=B_0 j exists in the region a

Correct answer

C. A magnetic field B=B_0 j exists in the region a

Step-by-step solution

∵\because Magnetic field due to a hollow cylinder of radius rr A uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field B Binside =0( for d<r)Boutside =μ02π⋅id( for )d≥r)\begin{aligned}B_{\text{inside }} &=0(\text{ for }d < r) \\ B_{\text{outside }} &=\frac{\mu_{0}}{2 \pi} \cdot \frac{i}{d}(\text{ for })d \geq r) \end{aligned}So, graph between$B and d.A uniform current is flowing along the length dinfinite, straight. thin. hollow cylinder dradius R The magnetic field B
