Ubiquitous computing and magnetic interference

Imagine the radio of a car, does the electro magnetic fields through which the car goes through, have interference in the processing? It's easy to understand that a strong field can corrupt data. But what about the data under processment? Can it also be changed? If so how could you protect your code against this? (without electrial prot...

Matlab: Magnetic fields calculated with biot-savarts-law

Hello! This is the code for the computation of magnetic fields using the biot-savart-law. I hope to get some tipps for the optimization of this code. Regrettably I use german language :( I never will do this again. :) tic clear all; clc; clf skalierungsfaktor = 10^-6; % vom m-Bereich zum mm-Bereich wg. T = Vs / m^2 I = 1; % in A konstan...
