As we all know, if there is a current in conductor, there will be a static magnetic field around it.If i simulate it using a 3D numerical model， i can get the static magnetic field. However, when i simulate it by a 2D axisymmetric model to reduce the computation , the magnetic field equal 0 ! Both model use the "elecric and magnetic field"and the boundary condition is same. WISH SOMEONE CAN HELP ME .THANKS A LOT.![]()
