I am studying the fundamentals of electrical engineering and no google answer has thus far been sufficient to me, so if you could help me out, then I would much appreciate it. I know that Voltage can be a square wave, sin wave, or DC (no oscillation), but what exactly makes an input signal from say a signal source oscillate? is it because of the magnetic fields created by current flowing? I'm not sure

Oscillation is caused by the interaction between a capacitor and an inductor. Given the right circumstances, they resonate. It is very much like the interaction between kinetic energy and potential energy in a spring system. The capacitor is similar to the spring (which stores P.E.) and the inductor is similar to the mass (which stores K.E.).

from wikipedia articles: "Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the

magnetic field in the inductor. This process is repeated continually. An analogy is a mechanical pendulum."
