NIW Property Requires Complex Tension Field (CTF)
Published in Chandrasekhar Roychoudhuri, Causal Physics, 2018
When we restructure Maxwell’s wave equation as in Equation 4.8 (just shown) to emulate the string wave equation, we can interpret ε0−1 as its intrinsic electric tension field (like T of the string) and μ0 as the countering response as the magnetic tension field (through the generation of magnetic field). Maxwell’s wave equation derives c2 = (ε0μ0)–1, which implies as if ε0 and μ0 play symmetrical role. We have chosen ε0−1 as the electric tension (stiffness) to emulate the string equation, because our detection methods dominate electric dipoles. Besides, magnetic properties emerge usually when moving charges exist. Our interpretation is that CTF possesses some physical properties such that material electric dipoles can enforce some of their energy into the CTF by triggering the emergence of an elemental electric field force (ε0−1sinθ). In reaction, the CTF tries to restore its state of equilibrium by generating the countering magnetic field force μ0x(∂2E/∂t2). Like the ideal long stretched string, the CTF does not have a mechanism to get rid of the energy already delivered into it by the dipole. So the local CTF keeps on pushing the perturbation away from the original site of perturbation, and hence we can observe, once generated, a perpetually propagating EM wave packet with a velocity c2 = (ε0−1/μ0).

Ordinary rotating electrical machines have two forces: Lorentz force and Maxwell force. The Lorentz force is generated by the current-carrying conductors cutting a rotating magnetic field, while the Maxwell force is the magnetic tension formed at the boundary of different magnetic permeability media. For the BIM, its rotation and suspension are performed by the Lorentz force and Maxwell force, respectively (He, Bu, & Li et al., 2017). The pole pairs of torque winding and suspension winding are recorded as P1 and P2, while the electrical angular frequencies are recorded as ω1 and ω2. Constant suspension force can be produced only when and (Wang & Huang, 2015; Zhan & Zhou, 2014). In this paper, the principle of suspension force is illustrated by the BIM with P1 = 2 and P2 = 1.
