## Main Question or Discussion Point

Hi

Can anyone tell me how magnetic field strength decreases with distance in free space? If the source was effectively a point souce in a plasma, what would the field strength be at a specific distance?

Is it source field strength/4 pi r sqrd?

As an example if the source was 1T, what would the measured field be at 5cm?

I've been reading some papers claiming massive field strengths inside dense plasmas and I'm curious as to how far these fields extend.

Thanks in advance
