Question Link: Here To solve this problem, we need to understand the balance of forces in the plasma and the magnetic field created by the current-carrying conductor. The equilibrium condition requires that the magnetic pressure from the azimuthal field \(B_{\theta}\) balances the plasma pressure \(p\) at the boundary of the evacuated hole. Let’s proceed step…
