Soft iron has a greater permeability than steel.
BTW, the only reason for laminations is to reduce eddy currents in the core. It has no effect on permeability or inductance.

Inductance
The inductance of a coil is not related in any simple way to the length of the wire or other conductor of which it is wound. The inductance is at least as heavily influenced by the diameter of the coil.
The coil consists of inductance. Due to inductance the current lags the voltage. So, the power factor is lagging.
I wouldn't. I doubt this is possible. Wire, by definition will have inductance. The inductance will increase as the frequency increases, so I guess you could specify a frequency that is extremely low to use the coil at.
The secondary coil will have greater inductance compared to the primary coil because it has more turns. The inductance of a coil is directly proportional to the square of the number of turns, so increasing the number of turns increases the inductance.
increase inductance
Type your answer here... By use an inductance meter or an inductance bridge
It is used to measure the inductance of a coil of unknown inductance.

To calculate a coil's self-inductance, you can use the formula L ( N A) / l, where L is the self-inductance, is the permeability of free space, is the relative permeability of the core material, N is the number of turns in the coil, A is the cross-sectional area of the coil, and l is the length of the coil.
Self inductance is a property of a coil that depends on the geometry and number of turns of the coil. The relative permeability of a material is a measure of how easily it can be magnetized. The self inductance of a coil can be affected by the relative permeability of the material in the core of the coil, as a higher relative permeability can increase the magnetic field and thus the inductance.
Mutual inductance describes the process by which a changing current in one coil, creates a changing magnetic flux which, when it links with a second coil, induces a changing voltage into that coil.
The inductance of a coil is not related in any simple way to the length of the wire or other conductor of which it is wound. The inductance is at least as heavily influenced by the diameter of the coil.
Since a coil contains numerous loops, more of the conductor is affectedÊ by the magnetic field. An increase in permeability of the core results in an increase in the inductance of the coil.
