Help please

I dont know why this circuit behaves in the observed manner when i use this curious looking component in a circuit, what is this circuit component: "inductor" and how is it used?

An inductor is a passive component. It has the property of passing DC freely and holding off AC. It's the exact opposite of a capacitor which only passes AC and holds off DC. In your example you need to replace the inductor with a capacitor. Inductors are added in series when you want them to suppress a ripple and capacitors are placed in parallel. Applications include rectifier filtering, LC tank circuits and many many other. They are widely used in a sinewave generation circuits.

Current build up a magnetic field in the coil and when the current is remove the collapsing magnetic field will put the current back into the circuit giving the lamp another chance to lite. I think it's a cool circuit.

rflberg you are correct. In inductors the higher the current through them the bigger the magnetic field. Upon collapsing of the magnetic field residual energy remains in the inductor that supplies the load with the needed current when needed. Same applies for capacitors but as inductors are placed in series, capacitors are placed in parallel.
