Is that true a capacitor stores energy in the form of a magnetic field?
Alexnguyen12
Simple answer: Yes. If there's electricity, there is a magnetic field. I'm guessing that you're thinking that alternating current reverses current flow, as opposed to direct current. This isn't quite right. A.C. works by alternately advancing and reversing the movement of charge, basically pumping electricity down a wire. Capacitors store charge. That's all they do until some part of a circuit lets them release it. So a capacitor connected to an a.c. source will just store charge and a magnetic field will certainly be attached.

What do you call the force around a magnet?
the area of magnetic force around a magnet is called the magnetic field
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.
What happens to the magnitude of a magnetic field if the electric field that induces it increases the rate at which it changes?
The magnitude of the magnetic field is decreased
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
How does earth magnetic field affect a compass?
The earth's magnetic field acts upon the magnetic material of the compass needle, causing it to align to the field. Thus, the compass appears to point North, which is "magnetic north". Magnetic north and "true north" are about 300 miles apart.
What is the purpose of capacitor in the circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)

Does a capacitor store energy in form of an magnetic field?
Current stops going into a capacitor when it's voltage is equal to the supply voltage. From then there is no flow of current, so there is no magnetic field. Yet the capacitor remains charged and has energy to release if required.
A capacitor is a device which stores energy by?
Magic. Look up capacitors on wikipedia!!A capacitor stores electrical charges in its plates.Both wrong. A capacitor stores energy as an electric field developed in the dielectric between its plates. A good dielectric with high permittivity (once called dielectric constant) concentrates this field, allowing more energy to be stored in a capacitor having the same plate area and separation but a dielectric of lower permittivity.
Does a magnetic fIEld have an effect on a capacitor placed in between the plates?
Does a magnetic field have an effect on a capacitor when it is placed between the plates? Yes, a magnetic field between the plates of a capacitor would have some effect. Without more information it is difficult to determine how much.
If the capacitor store the charge from the magnetic field then the capacitor is called?
it wouldn't store a charge from the magnetic field, only the current induced on the circuit would be stored
Does an ideal inductor does not dissipate any energy it stores energy in the form of a magnetic field?
yes
Do magnetic fields store energy?
of course, they do. A research project show that a motor constructed with magnets at specific directions & positions can run for atleast 100 years without break.But the magnets are not to be disturbed & also they don't have to be charged

How does a tank circuit circuit work?
A tank circuit is typically a combination of 'capacitive' and 'inductive' circuits that exchange 'energy' back and forth. An inductor stores energy as a magnetic field, wheras a capacitor stores energy as a charge across plates. Ideally, the exchange between them would go on forever (back and forth like a game of hot potato) however, a slight replenishing signal is needed practically. By selecting the proper values of components, the rate, or frequency, of exchange can be determined.
How can electricity be stored?
In a way it can be. If a capacitor is connected to a battery, it will charge to the battery voltage. Then the capacitor can be discharged into a circuit to do work. But the capacitor doesn't store electrons, it stores an electrical field in the dielectric. If you mean storing the flowing electrons in a conductor, then they can't be stored except in a magnetic containment field such as in a cyclotron. A rechargable battery doesn't store electrons either, it stores energy in a chemical form which is converted to an electrical form when the battery is connected to a circuit.
Can energy be stored in the form of electricity?
Yes. That's exactly the situation in the magnetic field of an inductor (coil),or in the dielectric of a capacitor. Both of those circuit elements are energy-storage devices.
