Need help with an experiment

Hello, I need some help here.

 

I am looking for a formula for for Magnetic Field strength in meters Vs Current in Amps because most formulae are referring to Tesla rather than distance in meters.

 

thx

It depends on the geometry. For a long, straight wire, go here

The meter is not an appropriate unit for magnetic field strength.

Are you thinking of the H field which has units of amperes/meter?

Then (in the SI system) B(in Tesla)=4pi*10^{-7} H(in amp/meter).
