What explains this?
Is the attraction force determined from the surface field?
A larger magnet would have the equal value fore the surface field but a stronger attraction/repulsion force?!
RE: Equal surface fields? Different pull forces?
The force is in (lb).
RE: Equal surface fields? Different pull forces?
The surface field is a flux density. The total flux is a product of the density and the area of the face.

RE: Equal surface fields? Different pull forces?
However, I seem to noticed that the force is dependent on the area, the larger the area the more space the flux line can pass and the force is greater.
RE: Equal surface fields? Different pull forces?
When the surface area of the magnet is = to the surface area of the other magnet or magnetic object, the magnetic force of attraction/repulsion is at its heights.

The force tend to change between magnet
RE: Equal surface fields? Different pull forces?
for some reason I got log into my account... So I made a new one.
The force between the magnets is a lot more complicated than what I've thought. Thats what I can say...
RE: Equal surface fields? Different pull forces?
It is not so, the way in which you perceive is more important. Consider what are the criteria will affect for of a magnet.
Take a simple example and get into basic understanding.Lets take steel and magnet of area 10 mm^2 of both and volume be 1000 mm^3
Here are few
Distance between the magnet and steel
Grade of the steel
Grade of the magnet
Set ideal condition to compute force then try with diffrent option by varying parameters which you're interested

I just noticed, that when I bought te magnets. They are rated at 5lb of force maximum.
I discovered, in order to get that MAX. force of 5lb the object has to be strongly magnetic and the surface area where the force is applied has to be equal to the magnet or greater and you find that force to be significant!
