What is that which is magnetic force? I believe a magnetic field is caused by movement of charged particles. But, what is it that is actually making the force between two magnets repel or attract to another? For repelling, I'm mentally visualizing a water balloon between two magnets. What is the water balloon composed of? Is it purely the "magnetic field"? If so, seems like more work needs to be done.

The interaction between electric (magnetic) fields from two sources is described by virtual photons. Virtual means, not existing in reality. So the real interaction between such fields is explained only in a statistical way and not in detail.
As long as the inner structure of these fields isn’t subject of interest, as long a detailed description is not possible. Why this is of an interest? Because, if one would think about an inner structure of such fields, there is no way not to think about some components or quanta. These quanta have to have some extent and energy content. Ergo electric and magnetic fields have to be finite. This would be in contradiction to the current perceptions.

What is a compass? How is a compass used to find directions?
Magnetic field lines never intersect each other because
There will be two directions of the field at the same point.
Feild lines repel each other
Field lines follow discrete paths only
If field lines intersect they create a new magnetic field within the existing fieldTwo parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
