Steady current i flowing through a solenoid, whose core is made with a material of permeability mu . If core of the solenoid is abruptly removed then what current will flow through the circuit just after core is removed.

A solenoid is connected to a battery so that a steady current flows through it. If an iron core is inserted into the solenoid, then
