The self-inductance of a solenoid is increased when a soft iron core is inserted into it. This is because the soft iron core________?
AReduces the effect of eddy current
BIncreases the mutual inductance between the solenoid and the core
CDecreases the resistance of the solenoid
DImproves the flux linkage between the turns of the coil
Correct answer
D. Improves the flux linkage between the turns of the coil
Explanation
The correct answer is Improves the flux linkage between the turns of the coil.
