The magnetic field produced is proportional linearly to the magnitude of the electric current. Thus, larger the current is, the stronger is the induced magnetic field.

#vec(dB) = mu_0/(4pi)(Ivec(dl) X vec R)/R^3#

This gives magnetic induction for a conducting vector element #vec(dl)# carrying current #I# at a distance #vec R# from #vec(dl)#.

This is Biot-Savart's law.

This shows how the magnetic field #vec(dB)# is proportional to the current #I#.
