A current of 5A is passing through a non-linear magnesium wire of cross-section 0.04m2. At every point the direction of current density is at an angle of 60° with the unit vector of area of cross-section.
The magnitude of electric field at every point of the conductor is :
(Resistivity of magnesium ρ=44×10−8Ωm )
