To make this a discussion about slinging, I'll mention that slinging a conductive material, i.e. steel or lead through the magnetic field of the earth causes a retarding force. The retarding force is a function of the conductivity of the projectile and the angle through which it travels relative to the magnetic field of the earth. As a consequence, throwing a lead projectile east or west will result in a shorter range than throwing north or south. If I got that mixed up, will one of you please let me know. It has been a while since I've used the right hand rule for electicity and magnetism.
Now about your questions:
I'm not sure what materials I want to specialize in. Thanks for asking! This decision is supposedly supposed to become more obvious as one finishes their education. In particular the technical elective courses are the means to help the student narrow it down. I have to take four more technical elective courses. Two of which I'm currently taking. I'm taking Electrochemistry/Corrosion and I'm taking Environmental Chemistry. Most of my materials classes I've taken recently are incredibly theoretical/analytical and very dry. I'm not happy with my education so far. My professors don't seem happy either. I think they all would rather do research than teach! And since they would rather do research they tend to teach at a level that assumes that we are doing independent lab work and research and otherwise we are entirely competent in materials science! But having said that I feel interested (but not competent) in rechargable battery technology and PV technology(photo-voltaic). I don't know what technical electives I will take next semester and I welcome any and all advice!
Now about your other questions:
I'm not getting a PHD! All I know about flux lines are that they represent magnetic fields. So I don't know anything about flux lines that approach the visible spectrum. If you're serious, please tell me what you mean. It sounds interesting.
Quote:What materials do you hope to specialize in? Have we even heard of them yet? Make us some transparent aluminum when you get a chance!
I want you to create a magnet whose flux lines approach the visible spectrum....such that a special viewer can see them in 3D. When such a magnet can be realized which virtual photons are used to produce light that is visible to the naked eye.....how fun would that be!
