How to calculate the repulsion force between a permanent and an electromagnet?

[Kirua]

Both the permanent and electromagnet will be constrained within a cylindrical tube (both magnets will be of cylindrical shaped, and have more/less the same cross sectional area). I want to know if its possible to calculate the repulsion force, in lbs, between the magnets, with a distance increment of 0.25cm.

Ideally, I wish to have the strength of the permanent magnet match closely to that of the electromagnet, or vise-versa. Will having matching strength magnets be the ideal set up to yield the greatest repulsion?

Thanks ahead of times!

Unfortunately, it is not possible to calculate the exact repulsion force between the magnets with a distance increment of 0.25cm. This is because the repulsive force between magnets depends on several factors, such as the relative orientation of the magnets, the strength of the magnetic field, and the relative size and shape of the magnets. Therefore, it is impossible to calculate the exact repulsion force without taking all these factors into account. As for whether having matching strength magnets will be the ideal set up to yield the greatest repulsion, the answer is that it depends on the other factors mentioned above. If the relative orientation and the size and shape of the magnets are appropriate, then two magnets with equal strength should yield the greatest repulsion. However, if any of these factors are not ideal, then two magnets with different strengths may yield a greater repulsion than two with equal strengths.
