Detailed Solution

Ferromagnetic substance will attack more number of magnetic lines through it. So, flux passing through it will increase. Hence, coefficient of self-inductance will increase. L depends on number of turns in the coil’s radius of coil etc. It does not depend on the current passing through it.
