Websince the curl of a gradient is automatically zero. across an irrotational vector field in physics we can always write it as the gradient of some scalar field. This is clearly a useful thing to do, since it enables us to replace a vector field by a much simpler scalar field. The quantity in the above equation WebThe vector potential A describes magnetic fields that possess curl wherever there is a current density J (r). In the space free of current, and thus H ought to be derivable there … pallanchathanurWebNov 24, 2015 · 1 For a steady-state current, the relation must hold div J = 0. This implies ∂ ∂ t ρ charge-density inside the volume = 0. This further implies during infinitesimal time-interval ∂ t, there has been no net consumption or depletion of charge inside the volume. Doesn't that mean J has the same value behind & in-front of the volume? pallam download
