If we place a current-carrying solenoid near an induced solenoid with a copper core inside it, is there any induced current?

If we place a current-carrying solenoid near an induced solenoid with a copper core inside it, is there any induced current?It depends on the current. Does it change with time?

The current is alternating.

The current is alternating.
Then there is a time-dependent magnetic field from the first solenoid. This extends out to the inside of the other solenoid. The other solenoid consists of conducting loops of wire. What does Faraday's law say regarding a time dependent magnetic field surrounded by a conducting loop?
