Vedclass · Answer

(B) Soft iron is a ferromagnetic material with high magnetic permeability. When a ferromagnetic material is placed in an external magnetic field,it becomes strongly magnetized. Due to its high permeability,the magnetic field lines prefer to pass through the soft iron rather than the surrounding air. This results in the concentration of magnetic field lines inside the soft iron bar,as shown in Figure $(B)$.

$A$ uniform magnetic field,parallel to the plane of the paper,exists in space and is initially directed from left to right. When a bar of soft iron is placed in the field parallel to it,the lines of force passing through it will be represented by:
