SUMMARY

The discussion centers on the behavior of induced current in a search coil inserted into a solenoid with a uniform magnetic field. When the search coil is moved through the solenoid, the electromotive force (emf) generated will increase as the coil approaches the solenoid, remain constant while inside, and then decrease as it exits. This behavior is attributed to the uniform magnetic field created by the solenoid, similar to that of a bar magnet. The participants clarify that there is no current in the middle of the solenoid itself, emphasizing the importance of understanding the magnetic field dynamics.

  • Investigate the behavior of search coils in varying magnetic fields
  • Learn about the applications of induced currents in practical scenarios
USEFUL FOR

Physics students, educators, and professionals interested in electromagnetism, particularly those exploring the principles of electromagnetic induction and solenoid applications.

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
