Why does a simple experiment contradict a rule of electromagnetism?

A simple experiment was conducted using a simple device.
Like poles of a permanent magnet and an iron-core solenoid (electromagnet) were set for repulsion using the device.
At first repulsion force was produced between the like poles. The iron-core solenoid crossed some distance over the fixed permanent magnet because of the repulsion.
Then the electromagnet moved back automatically and ceased to move (in the same position); While the current for repulsion was still put-on.
The iron-core solenoid needed a reasonable amount of force to be expelled from the magnetic field of the permanent magnet. It meant the strange attraction force that pulled the electromagnet back was substantial, not ignorable. The current for repulsion remained continuously put-on.
This experiment further proved that opposite polarities existed in the core instead of a single polarity. Both polarities interacted with the permanent magnet one after the other; separately, individually and independently. So repulsion and attraction forces were also produced separately and independently.
Interpretation of the experiment:
If an iron core is under influence of both of the magnetizing field H1 of the current in the coil and the magnetizing field H2 of the permanent magnet:
1. When the polarities of both magnetizing fields are like-polarities, opposite polarities are created in the iron core. One of the polarities will be a like polarity and the other polarity will be an unlike polarity in relation to the polarity of the permanent magnet.
2. When the polarities of both magnetizing fields are unlike-polarities, single polarity is created in the iron core. The current in the coil creates this polarity and the permanent magnet strengthens it. No matter what of both magnetizing fields is weaker or stronger, the polarity remains always the same.
On the other hand, a rule exists in electromagnetism that contradicts the interpretation:
“The iron core is magnetized by the magnetizing field H1 of the currents in coil and by the magnetizing field H2 of the magnet as felt at the location of the core. Whichever is stronger, H1 or H2, will determine the polarity of the core and the attraction or repulsion”.
Why are the interpretation of the experiment and the rule contrary to each other? Is the interpretation wrong or the rule is an overgeneralization?
