I have the fundamental understanding of how tokamaks work. Now, why is it not ideal to confine plasmas using a z- or theta- pinch configurations?

Oh sorry, I was to compare the densities of several elements(of varying masses, of course). But now using this formula for the radius, we end up with a constant which applies for any mass(as you've explained previously, the radius equation is derived). So now how am I to find the varying radii...

Yes I get what you're saying now. Now how do I get the radius for the density calculation?

I have just found it on wiki. How must I find the density then? how am I to find the radius of the iron nuclei to apply on the volume equation?

Homework Statement I am to calculate the density of a nucleus, say, of Iron, with mass 55.845 amu. Homework Equations see below The Attempt at a Solution I come to notice that all elements have the same value for the volume if I use the formula: $$mass=m=m_{amu}(1.66\times10^{-27}kg/1u)$$...

The problem statement does not necessarily say though that the circuit is a loop. The first equation explicitly states that it applies to a loop in a magnetic dipole. Can I still apply such equation for some circuit where a circuit element of it is under some magnetic field? And thank you, and...

Homework Statement We're given a situation where the circuit can move under the influence of a magnetic force. Now I need to show that the force on the magnetic dipole is Homework Equations $$\vec{F} = (\vec{m} \nabla) \vec{B} $$ The Attempt at a Solution Could I start from a given Force for...
