The strength of magnetic field along the axis of a solenoid coil increases on increasing the current flowing through the solenoid coil and on increasing the number of turns in the solenoid coil. Moreover, if a soft iron core is inserted inside the solenoid coil then magnetic field increases many fold.

The strength of magnetic field along the axis of a solenoid coil :a)in...
A. As the flowing current increase, no. of electrons through the solenoid increase and hence magnetic field and its strength will also increase.....
b. as the number of turns increase, density of magnetic field will increase and hence magnetic field and its strength will also increase....
c. as soon soft iron core come under the influence of electrical field, its starts acting as an magnet by utilising its mechanical properties.... hence all of above are true for the strength of magnetic field in solenoid.
b. as the number of turns increase, density of magnetic field will increase and hence magnetic field and its strength will also increase....
c. as soon soft iron core come under the influence of electrical field, its starts acting as an magnet by utilising its mechanical properties.... hence all of above are true for the strength of magnetic field in solenoid.

The strength of the magnetic field along the axis of a solenoid coil
The strength of the magnetic field along the axis of a solenoid coil depends on various factors. Let's discuss each option mentioned in the question to understand how they affect the magnetic field strength.
a) Increases on increasing current flowing through the solenoid coil:
When current flows through a solenoid coil, it creates a magnetic field. The magnetic field strength is directly proportional to the current flowing through the coil. As the current increases, the strength of the magnetic field also increases. This can be explained by Ampere's law, which states that the magnetic field inside a solenoid is directly proportional to the current passing through it.
b) Increases on increasing the number of turns in the solenoid coil:
The magnetic field strength along the axis of a solenoid coil also depends on the number of turns in the coil. The magnetic field lines generated by each turn of the coil add up to produce a stronger magnetic field. So, increasing the number of turns in the solenoid coil increases the magnetic field strength.
c) Increases on introducing a soft iron core inside the solenoid coil:
The presence of a soft iron core inside the solenoid coil significantly enhances the strength of the magnetic field. Soft iron is a ferromagnetic material that easily magnetizes and demagnetizes. When a soft iron core is placed inside the solenoid coil, it becomes magnetized by the magnetic field produced by the coil. This magnetized core strengthens the overall magnetic field. The presence of a soft iron core increases the magnetic permeability of the solenoid, resulting in a higher magnetic field strength.
d) All of the above:
From the explanations above, it is clear that all of the mentioned options - increasing the current flowing through the solenoid coil, increasing the number of turns in the solenoid coil, and introducing a soft iron core inside the solenoid coil - contribute to an increase in the strength of the magnetic field along the axis of the solenoid coil.
In conclusion, the strength of the magnetic field along the axis of a solenoid coil increases on increasing the current flowing through the coil, increasing the number of turns in the coil, and introducing a soft iron core inside the coil.
