The magnetic field induced in a material is independent of its thickness. Which of the following statements is correct?
- B = μ₀I / 2πr
- B = μ₀I / 2πr and so it is independent of thickness
- The current is same in both the wires, hence magnetic field induced will be same
- None of the above
Correct answer: B = μ₀I / 2πr and so it is independent of thickness
Solution
The magnetic field due to a current-carrying wire is given by B = μ₀I / 2πr, which depends on the current and the distance from the wire, but not on the thickness of the material.
