MR. ELECTRIC!

Hello all: I replaced the buggy dirac-delta mode with two new modes. The first is the ring charge mode, this creates a superposition of 36 point charges, which effectively simulates a continuous charged ring (not perfectly, but close enough to minimize error). This is especially useful for physics problems, as tons of them involve ring charges. Next, I added a mode that allowed you to change the permittivity of the space the charge is in, with a handful of presets ranging from the vacuum (free space) to pure water, all the way to titanium dioxide. In so doing, I also modified the guide and physics, enjoy these modes as you please. Furthermore, electric potential and electric potential energy were added to each mode, denoted by variables V and U. More additions to come in the future, stay tuned!

Hello all: I added a new background to make Mr. Electric feel less bland. I organized the information in the pages into blocks, this way it is easier to read, and less info-dumpy. I introduced a slider mode for the charges as well, this way you could drag the slider along and it would update the charge. Future changes are coming: Potentials, Electric Potential Energy, Better Dirac-Delta and more! Stay tuned!

Devlog 3: I added the ability to set a probe point on the first three run modes, the probe point will return electric field magnitude at that point, but it will also return the x, y and z components of that magnitude, so that anyone doing electrostatics problems can check their work as well. The graph now takes inputs in nanocoulombs, and it grows when larger inputs are put in, rather than changing the color. Guide and gallery have been updated to include these changes as well. Inputs have also been stacked neatly rather than arrayed one by one. Honest limits: One single color for all the plots, Gaussian mode not yet helpful because it still only contains one charge, and Dirac Delta is still just cosmetic! Future work will fix these!

It’s been a while since I’ve posted a devlog! This is Mr. Electric updates. I’ve brought the simulator into the html proper with a new simulate page. The code uses python connected to javascript. New features: Smoothed out the html and cleaned up any bugs. Added a simulate.html page where the simulator actually runs using Pyodide. Added dropdown options and menus to input values for the simulator. Future features: Planned expansion of simulator with more probe points, and drag and drop feature for probes. Ability to do actual calculations with the fields, and more dynamic fields that are prettier and smoother. Cleaner html and better style and buttons, including a unified nav style. 

This is the first devlog for my Mr. Electric project, its a small scale passion project designed to simulate electric fields with user input. I designed it over the span of about eight hours, alongside working the physics problems myself from Griffiths Electrodynamics Fourth Edition. Cursor assisted in debugging the code. The code uses NumPy, SciPy and Matplotlib. There are a few honest limits: I had to scale the arrows so nothing was generated close to the origin, the result was monstrous arrows because of the divide by zero issue. Dirac Delta is furthermore, simply a cosmetic feature. Dirac Delta represents particles, and graphically it is just an infinitely tall spike, I tried to simulate that in 3d and ended up with the current delta cluster. The project contains four run modes, one charge, two charge, Gaussian sphere plus probe and delta cluster. The main issue for this log was simply setting up the functions, and making sure everything worked! Up next is a public demo, more features, and a heatmap to help indicate relative vector strength.
