The definition of the polarity of the rotating magnetic field [Copy link]

As shown in the figure

Take one winding of one phase in a three-phase asynchronous motor as an example

The direction of the current is as follows

The four arrows in the middle are magnetic field lines (the diagram is perpendicular to the paper and facing inward)

The magnetic field lines of the four lines next to it are retracted (the picture shows that they are perpendicular to the paper and outward)

Shouldn't the magnetic field lines be emitted from the N pole and retracted from the S pole?

Is the magnetic polarity reversed in the diagram?

Outside the magnet, yes.

[Is the magnetic polarity reversed in the picture? ]

yes.
