3640 results about "Magnetic tension force" patented technology

The magnetic tension force is a restoring force (SI unit: Pa·m⁻¹) that acts to straighten bent magnetic field lines. It equals: (𝐁·∇)𝐁/μ₀ (S.I.) (𝐁·∇)𝐁/4π (c.g.s.) It is analogous to rubber bands and their restoring force. The force is directed antiradially. Although magnetic tension is referred to as a force, it is actually a pressure gradient (Pa m⁻¹) which is also a force density (N m⁻³). The magnetic pressure is the energy density of the magnetic field which can be visualized as increasing as magnetic field lines converge in a given volume of space.
