Malcolm Macgregor studied the nature and shape of the electron in his spare time while working at LLNL. After retiring he wrote 3 books. The book titled “The Enigmatic Electron” included corrections for Quantum Mechanical and Magnetic field.
The dark sphere is Macgregor’s concept of “Mechanical Mass” that does NOT have magnetic or electric field properties. The red colored sphere is defined as the electric point charge that sits at a 54.7 degree angle with respect to the horizontal plane of the “squashed” mechanical mass.
