[tex]F=m\frac{dB}{dx}[/tex]

(For simplicity I use only one dimension),

here

The magnetic field far from the magnet may be considered as a field from dipole. It is more difficult to consider the attraction of two attached magnet. One trick may help. Let's make a small air gap between two magnets. If we find out how much energy we can gain by reducing the air gap, we will find out the force, because

[tex]F=dE/dx[/tex]

Hi Shyboy...

Could you send me an example?

A commonly used equation to estimate holding force is:

[tex]F=0.577B^2 A[/tex]

where*B* is flux density in kilogauss, and *A* is the area of a pole face in square inches
