Magnetic field mass lines are always nearly normal to the surface of a ferromagnetic at every point. (This fact is analogous to the static electric field lines being normal to the surface of a conductor at every point.) Why ? |
| Answer» SOLUTION :Magnetic field lines are always nearly NORMAL to the SURFACE of a ferromagnetic at every point. The proof of this important fact is based on the boundary conditions of magnetic FIELDS (B and H) at the interface of two media. | |
