What area is referred to where ferromagnetic materials experience a force?

The concept of ferromagnetic materials reacting to a force is closely tied to a magnetic field. A magnetic field is generated by magnetic forces and is the area around a magnet where magnetic forces can be felt. When ferromagnetic materials, such as iron, cobalt, or nickel, are placed in a magnetic field, they experience a force due to the alignment of magnetic domains within the material. This force can cause the material to move toward the magnet or become magnetized itself.

In contrast, the electrostatic field refers to the electric forces between charged particles, which is unrelated to magnetism. The term "magnetic horizon" does not correspond with standard terminology related to magnetic fields or ferromagnetic materials. Similarly, a charged area implies the presence of electric charges rather than magnetic properties. Hence, referring to the magnetic field is the correct context in which ferromagnetic materials experience a force.
