Title: Any idea what is going on here?
Post by: Low-Q on September 14, 2016, 09:47:46 PM
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 :D

QUOTR FROM Gyulasun

I agree with Gyulasun, residual and induced magnetisim from the magnet and within the bearings / races.

I put a second magnet on the other side so S and N points in the same direction. There is no such thing going on then.
And "No", webby - I'm not nuts (this time), hoho  ;D

But there IS still time :)

Have you ever wondered,,

Since we "charge" these PM's to make them magnetic,, and since you can use the PM after it is charged to "charge" other things into becoming magnetic,,,

How many times can I charge some other object from a given PM before I will have a measurable drop in flux???

I have never actually tried to answer this question,, but I do have a lot of magnets from many years ago that are still the same now as they were then.
That is an excellent question! PM's has been viewed as super conductors since they keep the magnetism all the time. Maybe it's a clue right there? I don't know.
