current density = amperes/area

But 1 Tesla is given by formula below,which denotes that on a 1 meter long electrical conductor, which in turn conducts a current of 1 ampere, exactly 1 Newton attraction. 

             magnetic flux density formula tesla    

Therefore = 10^-1 effective current density.
