Ampere turn balance (MMF balance) in transformers

In summary: The Wikipedia article goes on to say:"When the primary is unloaded, magnetic flux from the primary coil leaks out of the transformer and makes up the series impedance. This flux is imperfectly coupled, and as a result, the primary and secondary coils have different amounts of flux associated with them. This difference in flux causes a voltage drop or rise in the secondary coil, which is why the secondary coil cannot balance the primary's leakage flux."

I believe your diagram is incorrect.
I was thinking the same, but seeing Jim's #34, it is electron current and not conventional current. So the right hand rule becomes left hand rule.

Conventional or electron current ?
Now i got to try it...
electron current

Yes. You're right.
