John: Look at the 1st picture. Port A is at the stage of very strong current flow. Meanwhile, Port B is at the stage of very weak current flow.

Me: Why?

John: Because, the direction of the current flow of both Port A and Port B is the same.

Note: The "black dots" of the picture above implies the direction of the current flow. You may take a look at this article. https://wodewangzhishime.blogspot.com/2022/06/an-england-spy-look-at-this-articles.html .

John: Look at the 2nd picture. If the direction of the current flow of the secondary coil is same as the direction of the current flow of the primary, the current flow of the primary coil will stop.
