Thank you! What I am trying to grasp, I guess, is where exactly the main source of all "mystery" or unexplainable behaviour connected to the "narrowing" by the measurement is. If a measured electron gets entangled with the measurement device upon measurement (even if we can't explain really what...
In my limited understanding of the quantum measurement problem, I am imagining the whole thing as corresponding to a kind of "weighting down" by a cascade of entaglement.
Here is my very simple understanding of the quantum measurement problem: A waveform (Schrödinger equation) describes the...
Ah ok, that could make sense I guess. So any tips on how I could calculate the force between a solenoid electromagnet and a iron object that is smaller than the magnet? I don't mind asuming ideal conditions of the iron object and magnet itself it this would simplify things!
Hello,
I need to calculate/estimate the force between a solenoid electromagnet and a piece of iron on a certain distance from the magnets airgap, preferable in a simple way under ideal conditions rather than a very exact calculation.
I have found the following formula at a couple of places...
