Would the Induced Current Change Direction Inside a Solenoid with a Search Coil?

AI Thread Summary
Inserting a search coil into a solenoid with its plane perpendicular to the magnetic field will induce a current that changes direction as the coil approaches the opposite pole. The discussion clarifies that the induced electromotive force (emf) will vary as the coil moves through the solenoid. Initially, the emf increases as the coil approaches the solenoid, remains constant while inside due to the uniform magnetic field, and then decreases as it exits. The participants emphasize understanding the behavior of induced currents and emf in relation to the solenoid's magnetic field. The conversation highlights the principles of electromagnetic induction in a solenoid setup.

if we were to insert a search coil inside a solenoid, (plane of coil perpendicular to B), would the induced current change direction in the middle of the solenoid ? it would have to wouldn't it since it would now be approching the opposite pole ---
??

What exactly do you mean? Can you be more specific here? What is search coil? Induced currents where? In the middle of solenoid? There is no current in the middle of solenoid.
 
sorry for the delay,
what i am trying to ask is basically this;
imagine a solenoid , with a current running through, creating a magnetic field basically like that of a bar magnet.
now if we were to take another coil( a smaller one) and move that coil through the solenoid, how would emf vary throughout that motion.
would it increase gradually as the coil cam closer to the solenoid and then hold a constant value whilst it is inside and then slowly taper off one it is out the other side of the solenoid. i am assuming this since the magnetic field inside the solenoid is uniform ...
thanks

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
