Homework Statement
In an atom: suppose one electron orbits the n proton nucleus at radius r . Find the magnetic energy density, in J/m3, at the center of the atom due to the motion of this electron.
NOTE: You can ignore the effect of other electrons in this atom.
Homework Equations
u=B^2/2*u_o
= (N*u_o*I)^2 /2u_o
or=N*(u_o*I)^2 /2u_o
The Attempt at a Solution
1)
Is the number of protons can be treat as the number of turns of the magnetic field, should I plug N inside the parentheses
2)
Since qvB=IBL and I get I=qv/L, and then I use mv^2/r = kqq/r^2 to get the expression of v and plug it in qv/L and finally plug the expression of I in the (N*u_o*I)^2 /2u_o.
Am I on the right track or it is completely wrong?
