Why Rutherford was wrong about the atom model?

Question 2: From the point of view of nuclear magnetic moment, the electron magnetic moment is way to large. Measurement tells us that nuclei usually have nuclear magnetic moment $$-3\mu_N$$ to $$10\mu_N$$ where $$\mu_N=e\hbar/2m_p$$ and $$m_p$$ is the mass of proton.
Hint: The magnetic moment is of the magnitude $$e\hbar/2m_x$$.
