I have two wires, each 1 meter in length. They are at a parallel distances (d) of 5cm from each other.(adsbygoogle = window.adsbygoogle || []).push({});

I send a current through one wire:I, and what I want to find is the current induced on the other wire:_{1}= 2 ampsI_{2}= ?

I can find B with the following formula (given a radius - which I could substitute with d):

B = μ_{0}I/2πr

For a transformer, I could find I_{2}using the following formula:

I_{p}= I_{s}(N_{s}/ N_{p})

(Where I_{p}is the primary current, I_{s}is the secondary current, N_{s}is the number of loops for the secondary coil, and N_{p}the number of loops for the primary coil) However, the transformers I know, all use a core of some sort - which will stretch the magnetic field.

Through my hours of searching, I have come across this formula:ΔF = ΔL(μ. I could solve for I_{0}I_{1}I_{2}/ 2 π d)_{2}but ΔF is still unknown here -I guess I could ask 'How do I find ΔF?,'never the less, perhaps there is yet another formula I'm missing out on?

I would like to know of a formula such as:I = f(B, v)where B is a force from say a permanent magnet, moving at a constant speed of v.
