Generating 3V-5V with magnetic core coil?

  1. Sep 3, 2013 #1
    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.
