How the charge oscillate in LC circuit?
If a charged capacitor is connected across an inductor, charge will start to flow through the inductor, building up a magnetic field around it, and reducing the voltage on the capacitor. Eventually all the charge on the capacitor will be gone and the voltage across it will reach zero. However, the current will continue, because inductors resist changes in current, and energy to keep it flowing is extracted from the magnetic field, which will begin to decline. The current will begin to charge the capacitor with a voltage of opposite polarity to its original charge. When the magnetic field is completely dissipated the current will stop and the charge will again be stored in the capacitor, with the opposite polarity as before. Then the cycle will begin again, with the current flowing in the opposite direction through the inductor.The charge flows back and forth between the plates of the capacitor, through the inductor. The energy oscillates back and forth between the capacitor and the inductor until (if not replenished by power from an external circuit) internal resistance makes the oscillations die out. Its action, known mathematically as a harmonic oscillator, is similar to a pendulum swinging back and forth, or water sloshing back and forth in a tank. For this reason the circuit is also called a tank circuit. The oscillation frequency is determined by the capacitance and inductance values used. In typical tuned circuits in electronic equipment the oscillations are very fast, thousands to millions of times per second.
How is a magnetic field produced in an atom?
This depends if they are charged or neutral and if they are moving or not. A: If they are not moving then nothing usually and if they are neutral nothing. B: If they are charged and moving then they begin to accelerate in the direction of the magnetic field. C: If the object is a magnetic object for instance Iron that shares its electrons metallically then it will feel a acceleration in the direction of the magnetic field all other object will feel nothing.
What correctly describes magnetic field lines?
The list of choices submitted with the question containsno correct description of magnetic field lines.
What material blocks a magnetic field?
There are no materials that STOP magnetic fields. Some have proposed that a faraday cage will stop magnetic fields, but this is not true because magnetism is a field, not a wave. The most effective way to block a magnetic field is to put a bunch of space between it and whatever's in trouble. Ideally, you could encase a magnet in a large plexiglass bubble to keep distance.
Why does not electrical current pass through a insolaters?
Electrical current does not pass through insulators because, unlike conductors, there is no lattice of free-floating electrons which can be attracted towards a charged end in a polar substance. In a conductor, the nucleus of the atoms all sit together while the electrons float freely around. When a current is passed through this, the electrons begin to be attracted to the positive end of the substance, however in an insulator the electrons are held tightly to the atoms they are attached to meaning that they are not free to move a current through the substance.

In a circuit where does the current begin?
The current flows from negative to positive.
The presence of a magnetic field indicates that a planet may have what?
A magnetic field indicates a ferrous core. This is necessary for life to begin because a magnetic field is needed to deflect solar radiation.
How do you test polarity with a multimeter?
A: To begin with the leads polarity of the meter must be ascertain. Assuming the red is positive voltage then that lead will have a positive potential to check a diode connect the red lead to the anode and the black to the cathode and it should read some Resistance
What words begin with the prefix nor?
Normal
When did magnetic therapy begin?
Magnetic therapy dates as far back as the ancient Egyptians. Magnets have long been believed to have healing powers associated with muscle pain and stiffness.
How did Earth's current era begin?
The beginning of Earth's current era is marked by a mass extinction.
What is meant by self-induction?
Any time charges move (like in a conductor), they build a magnetic field around their path of travel. The expansion of this magnetic field induces a voltage in that conductor that acts in a way to try to stop the charges that created it. Further, if charges are moving in a conductor, they have a magnetic field around their path of travel. And if the voltage that is causing the current to flow drops, the field will begin to collapse. The collapse of the field will induce a voltage that will try to keep the current flowing. This phenomenon is called self inductance. It (the self inductance) always acts in a way to resist a change of current flow in a conductor. That is the key point; it's the crux of the issue. A link is provided below.
Why does Ac current travel longer than Dc?
DC cannot travel very far until it begin to lose energy,but AC can be made high or low by "transformers".DC can also be transformed but it is a bit difficult than transforminf AC.AC transmission loses less energy because as current altenates the loss is reduced i.e when voltage is at +peak more loss and at -ve peak loss is less.in this way the loss is less in AC transmission.
