RMS to Peak Conversion: Magnetic Field Experiment

[spacetime]

I know that the RMS values need to be multiplied be 1.41 to get peak values, but now we are doing an experiment with magnetic field, there is a device that produces the magnetic field and the manual says we are supposed to multiply RMS values (which this device shows) by 2.82 to get the peak values. Can you please explain how it got doubled?

It depends specifically on the experiment and some kind of symmetry between the average value and the RMS value that gives you the factor to multiply by.

Note that $1.41 = \sqrt{2}$ and [itex]2.82 = 2\sqrt{2}[/tex][/itex]

Thanks, I understand now it's just for sinusoids that 1.41 or $$\sqrt{2}$$ is the factor.
