Any idea what is going on here?

I placed a neodym magnet on a 28mm ball bearing. Look what happens when i try to push it around.
Any idea why this is happening?

It's obviously being affected by the Iron Vise.

It's made of plastic. The same happens when I hold it in my hand.
It resists any movement like if it was a spring there to flip the magnet a little back when I release it.

I think the steel balls get magnetized and as they turn their poles trick normal movement as they oppose or attract the Neo magnet.
Such steel balls may have remanent magnetism too, so after a certain rotation this may also become a disturbing factor against normal mechanical rolling.

The strange thing is also when I move the magnet around and then hold it in position for a while, the magnet still "remember" from which direction it came from. I have never seen this before I bought a bunch of ball bearings for my other project when I discovered this.
And webby, the same happens if I hold the bearing with the magnet on in my hand - far away from any other metal parts.
In center or not, the same happens the oposite direction if I rotate the magnet the opposite way. So countertorque occurs in both directions. And that counter torque doesn't let go when I stop the magnet. Funny discovery
