Why air coil with soft iron core inductance is greater then air coil laminated steel core?

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.

What factors increase the inductance of a coil?
what factors on inductance drepends
What The property of a coil that makes it resist changes in current is called?
Inductance
What is the total amount of inductance measured in millihenries?
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.
Why current lagging in the coil?
The coil consists of inductance. Due to inductance the current lags the voltage. So, the power factor is lagging.
How would you wind a coil which has a resistance but essentially no inductance?
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.
Inserting a soft iron core into a coil has what effect on the inductance of a coil?
increase inductance
How do you measure inductance of a coil?
Type your answer here... By use an inductance meter or an inductance bridge
What is inductance comparsion bridge and its application?
It is used to measure the inductance of a coil of unknown inductance.

What is the meaning of mutual inductance as transformer works on the principle of mutual 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.
What is the total amount of inductance measured in millihenries?
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.
How does the permeability of a coil affect mutual inductance?
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.
Why current lagging in the coil?
The coil consists of inductance. Due to inductance the current lags the voltage. So, the power factor is lagging.

What is parasitic inductance of capacitor?
A: PARASITIC means like a parasite is there to offset the actual circuitry it can be inductance and/or capacitance A capacitor is usually wound in a coil this coil if frequency is hi enough will behave as a small coil has been added to the circuit. Hi frequency PWM capacitors have indeed four lead to reduce not eliminate this inductance
