- TL;DR Summary
- when a capacitor starts discharging, why is the induced magnetic field in the inductor in the same direction of the current? isn't it supposed to resist changes in current?
Let's say we have an LC circuit and we begin with the capacitor fully charged, it then starts discharging, and currents begins to flow in the circuit, and a magnetic field is generated in the inductor because of the current flowing through it. My question is, why is the magnetic field in this direction (figure b)? this magnetic field implies that the induced current is in the same direction as the current coming from the discharging of the capacitor, but the inductor is supposed to resist changes in current, so shouldn't its magnetic field be in the opposite direction? same with figure f.
