Hello everyone!
Task: the conductor is affected by a given current pulse (duration 0.24 ns), the rate of rise and fall of the pulse is 100 kA / μs. Copper conductor has dimensions of 16x52x1 mm and is surrounded by an air sphere.
Problem: When solving my model the magnetic induction in the conductor does not change when the current changes. This produces an incorrect graph for the output voltage - it repeats the shape of the current, although the influence of inductance should be taken into account
Images: 1 - expected graphics. The voltage at the ends of the conductor should be as in the (3) graph, but it turns out that it only repeats the shape of the current (2) graph 2 - resulting voltage 3 - resulting magnetic field 4 - current pulse 5 - magnetic field parameters
My model (comsol 5.3a) - https://yadi.sk/d/JSfo8MDrAsdWEA
Thanks
