Nikola Tesla noted that the behavior of vacuum bulbs varies with the excitation of their internal gases, prompting him to create bulbs that exhibited unique rotating brush patterns and dynamic areas of brightness. He connected these phenomena to electrostatic forces, magnetic fields, and the inherent design of the glass. Tesla found that even minor adjustments in current intensity or electrode positioning could lead to entirely different behaviors within the bulb. His meticulous investigation of these interactions allowed him to enhance sensitive detectors, which outperformed the standard instruments used in the initial stages of wireless technology.
