in l.c.oscillation why the field in an inductor reduces to zero when charge on capacitor dissapears?

Question

Asthere is no charge available to flow so feild should be zero.

Answer 1

the capacitor only holds a charge it is not a battery...there for when line voltage is applied it discharges...and then it merely passes the electriciy through to the work when the circuit is broken the capicitor then accepts a charge to the point of "saturation" the capacitor can be completely disconnected from line voltage and still deliver a charge. However once the capacitor discharges it will not develop a charge because the semiconductor only holds free ions applied through line voltage and is not able to develope any charge because it is not in anyway like a battery.

Answer 2

The capacitor acts as a source and once depleted there is no accumulation of charge available to flow so the field around the inductor which requires charge flow (current), to produce a field is also reduced to zero.

Answer 3

You answered your own question. And, yes, no current flow = no magnetic field.
