Name:		python-MagnetiCalc
Version:	1.15.2
Release:	1
Summary:	MagnetiCalc calculates the magnetic flux density, vector potential, energy, self-inductance and magnetic dipole moment of arbitrary coils. Inside an OpenGL-accelerated GUI, the static magnetic flux density (B-field) or the magnetic vector potential (A-field) is displayed in interactive 3D, using multiple metrics for highlighting the field properties.

**What does MagnetiCalc do?**
MagnetiCalc calculates the static magnetic flux density, vector potential, energy, self-inductance
and magnetic dipole moment of arbitrary coils. Inside an OpenGL-accelerated GUI, the magnetic flux density
(<img src="https://render.githubusercontent.com/render/math?math=\mathbf{B}" alt="B">-field,
in units of <i>Tesla</i>)
or the magnetic vector potential
(<img src="https://render.githubusercontent.com/render/math?math=\mathbf{A}" alt="A">-field,
in units of <i>Tesla-meter</i>)
is displayed in interactive 3D, using multiple metrics for highlighting the field properties.
<i>Experimental feature:</i> To calculate the energy and self-inductance of permeable (i.e. ferrous) materials,
different core media can be modeled as regions of variable relative permeability;
however, core saturation is currently not modeled, resulting in excessive flux density values.
**Who needs MagnetiCalc?**
MagnetiCalc does its job for hobbyists, students, engineers and researchers of magnetic phenomena.
I designed MagnetiCalc from scratch, because I didn't want to mess around
with expensive and/or overly complex simulation software
whenever I needed to solve a magnetostatic problem.
**How does it work?**
The <img src="https://render.githubusercontent.com/render/math?math=\mathbf{B}" alt="B">-field calculation
is implemented using the Biot-Savart law [**1**], employing multiprocessing techniques;
MagnetiCalc uses just-in-time compilation ([JIT](https://numba.pydata.org/))
and, if available, GPU-acceleration ([CUDA](https://numba.pydata.org/numba-doc/dev/cuda/overview.html))
to achieve high-performance calculations.
Additionally, the use of easily constrainable "sampling volumes" allows for selective calculation over
grids of arbitrary shape and arbitrary relative permeabilities
<img src="https://render.githubusercontent.com/render/math?math=\mu_r(\mathbf{x})" alt="µ_r(x)">
(<i>experimental</i>).
The shape of any wire is modeled as a 3D piecewise linear curve.
Arbitrary loops of wire are sliced into differential current elements
(<img src="https://render.githubusercontent.com/render/math?math=\mathbf{\ell}" alt="l">),
each of which contributes to the total resulting field
(<img src="https://render.githubusercontent.com/render/math?math=\mathbf{A}" alt="A">,
<img src="https://render.githubusercontent.com/render/math?math=\mathbf{B}" alt="B">)
at some fixed 3D grid point (<img src="https://render.githubusercontent.com/render/math?math=\mathbf{x}" alt="x">),
summing over the positions of all current elements
(<img src="https://render.githubusercontent.com/render/math?math=\mathbf{x^'}" alt="x'">):
<img src="https://render.githubusercontent.com/render/math?math=\mathbf{A}(\mathbf{x})=I \cdot \frac{\mu_0}{4 \pi} \cdot \displaystyle \sum_\mathbf{x^'} \mu_r(\mathbf{x}) \cdot \frac{\mathbf{\ell}(\mathbf{x^')}}{\mid \mathbf{x} - \mathbf{x^'} \mid}"><br>
<img src="https://render.githubusercontent.com/render/math?math=\mathbf{B}(\mathbf{x})=I \cdot \frac{\mu_0}{4 \pi} \cdot \displaystyle \sum_\mathbf{x^'} \mu_r(\mathbf{x}) \cdot \frac{\mathbf{\ell}(\mathbf{x^'}) \times (\mathbf{x} - \mathbf{x^'})}{\mid \mathbf{x} - \mathbf{x^'} \mid}"><br>
At each grid point, the field magnitude (or field angle in some plane) is displayed
using colored arrows and/or dots;
field color and alpha transparency are individually mapped using one of the various
[available metrics](#appendix-metrics).
The coil's energy <img src="https://render.githubusercontent.com/render/math?math=E" alt="E"> [**2**]
and self-inductance <img src="https://render.githubusercontent.com/render/math?math=L" alt="L"> [**3**]
are calculated by summing the squared
<img src="https://render.githubusercontent.com/render/math?math=\mathbf{B}" alt="B">-field
over the entire sampling volume;
ensure that the sampling volume encloses a large, non-singular portion of the field:
<img src="https://render.githubusercontent.com/render/math?math=E=\frac{1}{\mu_0} \cdot \displaystyle \sum_\mathbf{x} \frac{\mathbf{B}(\mathbf{x}) \cdot \mathbf{B}(\mathbf{x})}{\mu_r(\mathbf{x})}"><br>
<img src="https://render.githubusercontent.com/render/math?math=L=\frac{1}{\I^2} \cdot E"><br>
Additionally, the scalar magnetic dipole moment
<img src="https://render.githubusercontent.com/render/math?math=m" alt="m"> [**4**]
is calculated by summing over all current elements:
<img src="https://render.githubusercontent.com/render/math?math=m=\Bigl| I \cdot \frac{1}{2} \cdot \displaystyle \sum_\mathbf{x^'} \mathbf{x^'} \times \mathbf{\ell}(\mathbf{x^'}) \Bigr|"><br>
