In a long magnet, the center has less attraction force?

[happyfunball]

I understand your point, but I have seen many videos on Youtube of steel balls passing the whole magnet a little, and then being pulled back. My guess is that the ball is being pulled back by S, not by N.

So, couldn't we deviate the path of the ball, after passing N, before reaching S, in the neutral area at the middle, with weaker magnetic field?

It's still the equivalent of trying to harness momentum to push a stator over a circular v-smot wheel's gate. The energy just isn't there to self sustain bro.

The answer your looking for is that the magnet is a polar device having two poles but each pole is distinct. The metal ball is not attracted to the magnet it is attracted to the magnetic poles, the ball is attracted to the north pole and is attracted back to it as it tries to leave the north pole to the magnet center. The poles are the centers of force(polar regions) and the magnet center(the Bloch wall) is an impolar region having no polarity as is seperates the two polarities. We could think of the bloch wall as a mirror, the north pole is a reflection of the south pole and vice-versa, but a mirror does not produce force it simply produces a reflection of it. If you place your ball at the bloch wall or center of the magnet it will be attracted to either pole with the same force as when the ball was approaching the magnet itself.

allcanadian, thanks for your explanation.

So, the magnetic attraction force of an individual pole (let we say N) is the same in all directions, including in the direction of the Bloch wall (center of the magnet)?

I'm not a specialist in magnets and in magnetic fields (I no even bought my first neodymium magnet yet). So I will ask for the help of the specialists in magnetic fields here:

In a long magnet, the center has less attraction force?

From the drawings I had saw in my life, I imagine that the magnetic field lines in a long magnet (cylinder or bar) are more or less how in the drawing I posted bellow.

Is it right? And if it's right, is the attraction force less powerful at the center of the long magnet? Could a steel ball escape from the magnet by going perpendicular to the center of the long magnet?

You wil find an "neutral Zone"

even between the poles from an hors-shoe-magnet- In the center of the flux.
(in air-agat - even in the center of the soft iron)

Correct, the magnetic pole is where you will find the greatest polar density which will create the greatest force on a metal ball. The magnetic pole (N) will create a magnetic pole (S) in the side of the metal ball facing it, thus they attract and inbetween the magnet (N) pole and the ball (S) pole yet another bloch wall will appear which is impolar(having no polarity). The permanent magnet has turned the metal ball into a magnet itself and this is why they appear to attract. Natural law states that any force will create an equal and opposite force and between these two forces will be a region of no force as it must seperate the two. This is called the "Trinity of Unity", one force divided must always produce three, two polar regions seperated by an impolar region dividing the two.
It is also said that opposites attract, if the (N) and (S) poles were attracted to each other then why are they not in the center of the magnet? If we consider that polarity is a stressed condition then we know that when stress is relieved it does not neutralize itself it simply ceases to exist. Thus the opposing polar stress (N-S) created in the magnet finds balance externally by voiding it's condition of polarity at the bloch wall. The (N) pole does not flow to the (S) pole, the poles destroy each other at the bloch wall, in nature opposites do not attract they destroy each other to find balance. We can show this voidance mathmatically by the simple equation (-1) + (+1)= 0 or the creation of polarity as 0= (+1) + (-1). The illusion here is that when we sprinkle iron filings around a magnet and see uniform field lines between the (N) and (S) poles we instinctively make an incorrect assumption when in fact the iron filings have simply turned into tiny magnets themselves and aligned with the field but there is always that persistent line which must seperate the poles. This rule also applies to Gravity and Electricity as they are polar forces, I wonder where all the supposed electricity in a battery goes? It would seem that the motion produced when two polar forces race to each other to destroy each other to find balance is what we consider work, Work=Force x Distance. In general the forces in nature are simple but the effects give the illusion of complexity, for some reason we are attracted to complexity and making everything harder than it need to be, that is our nature
