Generating 3V-5V with magnetic core coil?

Click For Summary
SUMMARY

Generating 3V to 5V using a magnetic coil is feasible by utilizing a high turn ratio in a changing magnetic field. Guitar coils typically produce 500mV to 1V, but with the right core material and sufficient turns, achieving the desired voltage is possible even with a magnetic field strength of 30μT. Key equations such as B = ∅/S and V = -N*d∅/dt are essential for calculations, but experimental data will enhance accuracy. Online coil calculators can assist in determining the necessary specifications.

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.
