In my experimental research on permanent magnet–electromagnet systems, I observed a net axial force generated not by the Lorentz mechanism, but by a direct combination of net repulsion and net attraction between magnetic sources. This Direct Magnetic Interaction (DMI) Force appears to arise from well-known magnetic laws (like poles repel, unlike poles attract), yet it doesn’t fit into classical electromagnetic models that rely on perpendicular force vectors.
The DMI Force is described simply as:
FDMI=FR,net+FA,net
It acts along the axis of interaction, not perpendicular to it, and enables permanent magnets to actively contribute mechanical work in motor systems. This mechanism has been verified through reproducible experiments and multiple working prototypes.
Could this suggest a gap in how magnetic force systems have been modeled, especially in the context of energy-contributing field sources? I would greatly value the insights, critiques, or references of fellow researchers.

For full detail, my recent preprint is available. This research is published for pre peer review refinement. The technology emerged from the research has already been patented by the U.S. after 3 years' extensive examination.
Title: Experimental Identification of a Novel Force Mechanism: The Direct Magnetic Interaction Force in Permanent Magnet–Electromagnet Systems
May be this can be addressed through:
· Modeling DMI using energy-based approaches: Compute ∇U, where U is the system’s field energy under PM-EM configurations.
· Using finite element magnetic simulations (e.g., COMSOL, FEMM) to validate axial forces under different geometries.
· Exploring whether DMI can be framed as a non-potential field force arising in certain symmetry-breaking magnetic configurations.
