Magnetic tension is the restoring stress associated with bending magnetic field lines. In a divergence-free field, the Lorentz-force density splits into a magnetic-pressure gradient and the tension term in SI units.

Magnetic tension is a concept in magnetohydrodynamics (MHD) and plasma physics that describes the tension force exerted by magnetic fields on conductive fluids or plasma. This force arises from the interactions between the magnetic field lines and the motion of charged particles within the fluid. To understand magnetic tension, consider the following: 1. **Magnetic Field Lines:** In a magnetic field, field lines carry the concept of magnetic flux.
