Any idea what is going on here?
« 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.

Welcome to the strange world of magnets.

Consider any metal within the area,, like the springs in the plastic clamp,, pins rings and so on,,

Nothing there you can see :)

Now try this,, largerish steel ball an a flat level table,, hold the magnet a long distance away and slowly bring it in to the ball,, WHAT the ball gets pushed away!  it will when done nicely :)

You have a hole in the middle of that bearing,, a piece of metal,, the magnetic field does not behave real nice with holes,, you have round steel balls that are polarized and as such do not give it up right away,, same with the cage.

In my way of looking at things you have created a mushy stressed field,, mushy meaning that is not fully polarized one way or the other and does not change instantly,, it takes time.

Most likely, the bearings have clearance and as such they create a torque between the inner and outer races,, so if they are sucked more to one side than the other the center of rotation is not about the inner race,, it will rotate to the point of lowest potential.

ADDED: I forgot to include that the magnet is also not necessarily in the exact center of the inner race,, creating its own torque.

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

Yes indeed,, funny things can happen with magnets.

You are not seeing things, nor are you nuts,, these things happen.

Take your magnet away from the bearing and quickly see if the bearing is retaining some flux,, I have watched it slowly "drain" away and drop a paper clip,, sometimes it stays for a long time,, not sure of what made the difference,, I just thought it was interesting.

I have coils that will "remember" the pulse polarity of the core that I gave them,, I can use large PM's to try and change it but when I remove the PM it goes back to what it was,, I can hit it with another EM field from another normal coil,, same thing,,  if I could figure out how to "drain" the core on command other than reverse the pulse polarity,, which only reverses the coil core polarity, that would be interesting.

QUOTR FROM Gyulasun

"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." END QUOTE

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.

I think that it has been discussed,, here or somewhere,, it is a little foggy memory :)

IIRC  the consensus was that the energy was actually put into the "charged" body by Mr. Hand when you pulled it away from the PM.

Not sure about that but it does make a nice rationalization.
