If we place a current-carrying solenoid near an induced solenoid with a copper core inside it, is there any induced current?
The discussion revolves around the concept of mutual induction in solenoids, specifically examining whether an induced current occurs when a current-carrying solenoid is placed near another solenoid with a copper core.
The discussion is ongoing, with participants examining the relationship between the time-dependent magnetic field and the induced current in the second solenoid. There is a focus on understanding the principles of mutual induction without reaching a definitive conclusion.
Participants are considering the effects of alternating current and the configuration of the solenoids, as well as the role of Faraday's law in the induction process.
It depends on the current. Does it change with time?phyphysics said:If we place a current-carrying solenoid near an induced solenoid with a copper core inside it, is there any induced current?
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?phyphysics said:The current is alternating.
