Induced V, due to self inductance?

AI Thread Summary
In a DC circuit, when current begins to flow, it takes time to stabilize, leading to an increasing magnetic field and changing flux that induces a negative voltage (V) opposing the current due to self-inductance. Once the current stabilizes, the induced voltage becomes zero. The discussion raises questions about how the current stabilizes despite the opposing induced voltage, suggesting that the power supply may need to apply additional voltage to maintain current flow. This interplay between induced voltage and current stabilization is crucial for understanding circuit behavior. The dynamics of self-inductance in DC circuits highlight the complexities of electromagnetic interactions.

In a DC circuit(Yes, keep going), when current starts to flow, and that current needs a bit of time to stabilize to its maximum value. Since there is change in current(increase) there is an increasing magnetic field, a changing flux... that will induce a -V to the circuit. Eventually when current stabilizes at t0, the induced V due to self inductance = 0 right?

But, how does current stabilize when there is that -V opposing it? Would the PS apply more voltage?

Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
