Generating 3V-5V with magnetic core coil?

AI Thread Summary
Generating 3V to 5V from a magnetic coil is feasible with a high turn ratio in a changing magnetic field. Typical guitar coils produce 500mV to 1V, but achieving higher voltages requires careful consideration of coil turns and core material. A magnetic field strength of around 30μT can be utilized for short-duration voltage generation. Relevant equations, such as B = ∅/S and V = -N*d∅/dt, are essential for calculations, though experimental data would enhance accuracy. Online coil calculators can assist in determining the necessary specifications for the project.

Hi guys,

I'm wondering whether I'd be able to generate around 3V - 5V with a magnetic coil using a high turn ratio in the presence of a changing magnetic field.

I know guitar coils can generally produce around 500mV - 1V, I wish to generate around 3V -5V even if it is for a very short time in the presence of a small changing magnetic field, say around 30μT in under a second.

What kind of core and how many turns of coil would I need? I have some equations here such as B = ∅/S and V = -N*d∅/dt but it is hard to do this without some experimental data.

There are numerous coil calculators online that can do that for you.

Just Google coil calculator online.

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...
