sheung.yeung Posted August 20, 2005 Share Posted August 20, 2005 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 Link to comment Share on other sites More sharing options...

Meir Achuz Posted August 20, 2005 Share Posted August 20, 2005 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). Link to comment Share on other sites More sharing options...
