Gauss for electricity
Charges create electric fields that spread outward. In radar terms: the voltage you push onto an antenna creates the field that will eventually become a wave.
Gauss for magnetism
There are no magnetic monopoles — every magnetic field line is a closed loop. This is why antennas must be designed as closed circuits; you can't have a 'one-ended' magnetic source.
Faraday's law
A changing magnetic field induces an electric field. This is how a receiving antenna works: the incoming wave's magnetic component wiggles electrons in your wire, and you read the voltage.
Ampère–Maxwell law
A changing electric field induces a magnetic field. Combined with Faraday's law, this is the engine of wave propagation: each component regenerates the other as the wave moves through space at c.
Why it matters for a player
When SignalLock shows you a faint blip, the entire chain — your transmitter's pulse, the target's reflection, the dish's reception, the screen pixel — is Maxwell's four equations executing in real time.
