SUMMARY
The discussion centers on the phenomenon of mutual induction between two solenoids, specifically when a current-carrying solenoid is placed near another solenoid with a copper core. It is established that if the current in the first solenoid is alternating, it generates a time-dependent magnetic field. According to Faraday's law of electromagnetic induction, this changing magnetic field induces a current in the conducting loops of the second solenoid. Thus, an induced current is present when the conditions of alternating current are met.
