Electronic device turned on in presence of tesla coil

AI Thread Summary
A small Tesla coil with a 1-foot secondary and 3-inch leaders can induce voltage in nearby conductive objects, such as an LED bike blinker, due to the high electric field it generates. This phenomenon is similar to the effects produced by Van der Graaf generators. The induced voltage can potentially damage electronic devices, making it crucial to maintain a safe distance from sensitive equipment like computers and TVs. Proper shielding is necessary to protect electronics from these high-voltage effects. Understanding these interactions is important for safely operating Tesla coils and similar devices.

I had a small, about 1 foot secondary tall tesla coil with about 3 inch leaders coming off the toroid, and when i turned it on, I had an LED bike blinker light that would turn on when I would turn on the tesla coil. The blinker was about a foot away from the coil. I was wondering if anyone knows why it might have turned on.

Van der Graaf generators produce similar effects.

It is due to the very high electric field being generated and any nearby conductor that is not adequately shielded can have a large voltage induced in it.

Such devices can destroy electronics and need to be kept well away from video recorders, TV sets, computers etc.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
