How does a capacitor affect a magnetic field?

As a current i, given by dq/dt and pointing down in the inductor, is established, the capacitor's charge decreases, causing the energy stored in the electric field within the capacitor to decrease. This energy is transferred to the magnetic field that appears around the inductor due to the building current i.

Can a capacitor and inductor oscillate without a source of EMF?

It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively. A circuit containing both an inductor (L) and a capacitor (C) can oscillate without a source of emf by shifting the energy stored in the circuit between the electric and magnetic fields.

What are electromagnetic oscillating circuits?

In the previous sections we have discussed electromagnetic oscillating circuits, where the energy Wel oscillates periodically between electric field energy in capacitors and magnetic field energy in solenoids.

How many Ma does a capacitor have in an oscillating LC circuit?

In an oscillating LC circuit, the maximum charge on the capacitor is 2.0 × 10−6 C 2.0 × 10 − 6 C and the maximum current through the inductor is 8.0 mA. (a) What is the period of the oscillations? (b) How much time elapses between an instant when the capacitor is uncharged and the next instant when it is fully charged?

What happens when a capacitor is closed?

This energy is When the switch is closed, the capacitor begins to discharge, producing a current in the circuit. The current, in turn, creates a magnetic field in the inductor. The net effect of this process is a transfer of energy from the capacitor, with its diminishing electric field, to the inductor, with its increasing magnetic field.

What are electromagnetic oscillations in a simple LC circuit?

In a simple LC circuit, the oscillations of the capacitor's electric field and the inductor's magnetic field are referred to as electromagnetic oscillations. Such a circuit is said to oscillate. (Parts a through h of Fig. 31-1 illustrate the succeeding stages of these oscillations.)
