A uniform magnetic field parallel to the plane of paper, existed
in space 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 figure
Show answer and solution
When a bar of soft iron is placed in the uniform magnetic field
which is parallel to it because of large permeability of soft iron,
magnetic lines of force prefer to pass through it. Concentration of
lines in soft iron bar increases as shown in figure.
