General Solution to Magnetic Potential in Region III
Similarly, in the magnet region, we take into account the presence of a magnetic field to evaluate the potential vector as follows:
(25)
Where , are constants related to the boundary conditions. is the magnet skin depth defines as: [58]
(26)
Knowing the potential vector, we can calculate the magnetic inductance and the electric field in each region of the machines as follows:

The computation of the magnetic field H, considering the non-linearity of material is possible by using the Marrocco formula[59]:
(30)
Where α, τ, ε, and c are positive constants determined by using magnetic characteristic of the material.

Furthermore, the structure's configuration, building materials, and influential forces all play a great role in failure.
The prediction of the relationship between water, building materials (such as soil), and the structure itself makes it difficult to comprehend the breach features or parameters of an earth embankment [10, 22, 23].
Generally, the comparative results produced by these models have a magnitude since most of them did not consider erodibility, which depends on nature and the compaction uncertainty of construction materials.

The syngas can be produced using CO2 as one of the starting materials.
A concept similar to that used for the thermochemical production of H2 from H2O using metal oxide materials and the heat generated from solar furnaces to heat these materials could be applied for CO2 too (eqs. 16 to 18) [242-244].
