If you spin a cylindrical magnet will anything happen to its magnetic field?

    If the magnetic poles are at the ends of a perfectly symmetric permanent magnet cylinder and and you spin the cylinder around its central axis, will anything happen to the magnetic field?

    I feel like something should happen since the magnetic domains are revolving around, but the field is symmetric about the axis.

    For permanent cylindrical magnets, if the poles are on the flat surfaces, if you spin the cylindrical magnet on its axis, clockwise or counterclockwise or both at regular/rapid frequency, pulses, nothing will happen to the magnetic field, it won't change to the outside observer.

    If you spin the cylindrical magnet in a way for example, if it's a disc and you flip it like coin, the magnetic field will rotate with it but the overall magnitude and field shape will remain the same.
