What Are Boundary Conditions?

1.	What Are Boundary Conditions?
Answer» There are four basic rules for boundary conditions at the surface between two different materials: The tangential components of electric field INTENSITY are continuous across the boundary. The NORMAL components of electric FLUX density are DISCONTINUOUS at the boundary by an AMOUNT equal to the surface-charge density on the boundary. The tangential components of magnetic field intensity are discontinuous at the boundary by an amount equal to the surface-current density on the boundary. The normal components of magnetic flux density are continuous across the boundary. There are four basic rules for boundary conditions at the surface between two different materials:
