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.
Which is true of magnetic field lines but not electric firld lines apex?
Magnetic field lines always form closed loops, while electric field lines begin and end on charges. Additionally, magnetic field lines do not originate from monopoles, while electric field lines can begin and end on electric charges.
When a magnet is moved alongside a wire what happenes?
the electrons in the wire begin to flow
What is true about magnetic field lines but not electric filed lines?
Magnetic field lines form closed loops, while electric field lines start and end on charges. Also, magnetic field lines do not begin or end; they always form continuous loops.
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.

When a magnet is moved alongside a wire what happens?
the electrons in the wire begin to flow
In a circuit where does the current begin?
The current flows from negative to positive.
What words begin with the prefix nor?
Normal
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
At what age is it considered normal for individuals to begin masturbating?
It is considered normal for individuals to begin masturbating during puberty, typically around the ages of 12 to 15.

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.
