mishima said:Since you have the symbol for DC voltage on your schematic, the answer is that there isn't a current there.
If you meant AC, to the right. Basically the second solenoid is an upside down version of the first, with magnetic field pointing down.
davenn said:outside what ?
did you understand mishima's comments in post 2 ?
that is did you really mean to show AC and not DC as you did ?

View attachment New Doc 1.pdfyes, because in starting the voltage increases but when it reaches its maximum value then the changing flux saturates and therefore there is no rate of change of flux and hence current will stop flowing in the secondary.davenn said:with the DC as yuo have shown, there will only be a very brief moment that current will flow in the secondary coil
and it will be in the opposite direction to the current flowing in the primary.
As soon as the current and hence the magnetic field in the primary reaches maximum ( and no longer varies)
current will stop flowing in the secondary.
Do you understand why?

The current direction at the 'P' point in a transformer is important because it determines the direction of power flow and the efficiency of the transformer. It also helps in understanding the behavior of the transformer under different load conditions.
The current direction at the 'P' point is determined by the relative direction of the primary and secondary windings. If the windings are in the same direction, the current will flow in the same direction. If they are in opposite directions, the current will flow in opposite directions.
The current direction at the 'P' point can be affected by the number of turns in the primary and secondary windings, the magnetic properties of the core material, and the frequency of the input power.
If the current direction at the 'P' point is reversed, the transformer will not operate properly. It can cause overheating, voltage fluctuations, and even damage to the transformer. It is important to ensure that the current direction is correct before operating the transformer.
The current direction at the 'P' point can be changed by reversing the direction of the windings. This can be done by physically rewinding the transformer or by using special transformer connections. However, it is important to consult a professional before attempting to change the current direction, as it can have negative effects on the transformer's performance.
