    Magnetic field energy of electron

    I've got a question regarding the magnetic field of an electron, and wheter or not it has some form of "self inductance" or resistance to be put in motion. The magnetic energy per volume is equal to u= 1/2*μ*H2. Say I've got an electron at rest, then the energy of the magnetic field is zero...

    Electron accelerating in a bent wire

    If I run a current through a wire with a 90 degree turn, what prevents the electrons from continuing out of the wire is a straight forward path? What force accelerates them in the direction of the wire?

    Why won't two objects stick when put tightly together?

    Hey, I was just thinking a bit about vacuum and air pressure and suddenly came over something really simple I cannot explain. I know that it is the external air pressure that makes two halves of a hollow sphere containing vacuum stick together like in this picture...

    What courses to take in addition to engineering physics?

    Hey, I am strongly thinking of switching from mechanical engineering over to engineering physics. I am thinking of taking the first year again, and will therefore have about 5 courses I can choose freely. So the question is, what courses could be a nice addition to a engineering physics degree...

    Engineering Applied mechanics vs. engineering physics

    Hello! I am currently doing my first year in a mechanical engineering degree(which after a few years branches off to applied mechanics), which is a 5 year integrated master's. Since before i applied, I have been uncertain about which study I really want to/should do, and that uncertainty still...

    Engineering Nanotechnology or mechanical engineering

    Hi! I am now doing my first semester for an integrated master's degree in mechanical engineering at a Norwegian university. I am doing well, but I have been second-guessing my choice for a while now. I have to admit I really was uncertain about what to chose, and while I mainly considered...
