hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I have to determine if a magnometer is able to detect variation of a magnetic moment. I am given the following observations:

n = 2.7* 10^{21}(number of particles)

mu = 2*10^{-20}Am^{2}

detection limit = 10^{-19}

than I am given the variance of the magnetic moment as

[tex]\sigma^2(m) = \frac{2}{3}\mu^2[/tex]

The question is can the variations in the magnetic moment be detected?

I am a little bit lost how to proceed - any hints or advise appreciated

Thanks in advance

Best
