One of the standard tests to gain an EMC Compliance Certificate is a spark discharge test.

Any experienced engineer will have a Spark Generator (Car Ignition coil, spark gap and short Dipole) to test to see if his latest project misbehaves when confronted with Impulse Interference.

As an EMC Investigator I would always carry a spark generator to demonstrate to newby engineers why EMC Compliance is so important.

I've seen a spark from 50ft away crash or reset a microprocessor system. Just the static discharge from walking on carpet is often enough.




This is not the same thing. The cause is from the burst of light, not EM.


What if I told you that light is EM?


I would tell you that pretending there isn't an implied distinction for everyone involved in a modicum of applied science is as counterproductive as arguing about the editor chosen for a coding tutorial.
