Homework Statement



Hello,
I am working on a project in which hollow carbon steel metal balls(1.5" diameter)(weighing 127.005g a piece) are placed in a plastic tube (1&5/8" innner diameter). Surrounding the plastic tube is enamel coated magnet wire(coiled around the plastic tube) in which a current(12 volts) is passing through the wire thus creating a magnetic field. My question is will the magnetic field be strong enough to lift the balls. Also what is the maximum weight that magnetic field produced can lift? Please include equations used. If you need any more details please feel free to ask. Thank You

Why do you think the steel balls will be lifted by any sort of magnetic field?
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...

The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
