The magnetic flux rises when an iron core is introduced into the solenoid. According to Lenz’s law, as the flux increases, the current flow through the coil decreases.
A solenoid is connected to a battery so that a steady current flows through it. If an iron core is inserted into the solenoid, will the current increase or decrease? Explain.
