purpose of steel core in stator of Alternator

"The magnetic core of coil is a better path for magnetic lines of force than is the nonmagnetic core of coil. The soft-iron magnetic core's high permeability has less reluctance to the magnetic flux, resulting in more magnetic lines of force. This increase in the magnetic lines of force increases the number of lines of force cutting each loop of the coil, thus increasing the inductance of the coil."
