how does the strength of the magnetic field increases when a soft iron is introduced in a solenoid?

The strength of the magnetic field increases when a soft iron is introduced in a solenoid because the iron is magnetised by induction.
 
When a current is passed through the wire wrapped around the iron, its magnetic field penetrates the iron, and causes the magnetic domains inside the soft iron to turn, aligning parallel to the magnetic field, so their tiny magnetic fields add to the wire's field, creating a large magnetic field that extends into the space around the magnet.
 
The larger the current passed through the wire coil, the more the domains align, and the stronger the magnetic field is.

Plssss answer..... Assertion: Magnetic field lines never intersect each other. Reason: If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
