A long straight wire with a circular cross-section having radius \(\mathrm{R}\), is carrying a steady current I. The current I is uniformly distributed across this cross-section. Then the variation of magnetic field due to current I with distance \(r(r<R)\) from its centre will be : 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
