Ultimate results of the dynamics of imperfect magnet poles are unbelievable and totally contrary to present sense about permanent magnet force.
Above statement proves that permanent magnet interacts differently with an iron-core-solenoid and with an air-core solenoid.
Lack of knowledge about the dynamics is shocking. This knowledge cannot be deduced from prior knowledge.No use of trying to count the teeth of a horse without opening the mouth.

Electric motors that depend on the repulsion of iron-cored solenoids work fine .

No one is disputing this, just your interpretation of why it happens. As has been explained to you in previous topics, it's always necessary to consider the complete magnetic circuit and relative reluctances of the flux paths. If the circuit allows a lower reluctance flux path through the core (or any magnetically permeable neighbour), then the permanent magnet flux will influence the core and you see the weaker repulsion/stronger attraction. The mechanism is fully understood and has nothing to do with perfect and imperfect poles.Quote from: investigator2100 on 05/06/2019 02:59:54Lack of knowledge about the dynamics is shocking. This knowledge cannot be deduced from prior knowledge.No use of trying to count the teeth of a horse without opening the mouth.Magnets, both permanent and electromagnets, and magnetic material, are very important to our modern society and so have been studied extensively. No effect such as you are proposing has been noted.The horses mouth has been opened regularly and the teeth examined in detail.
