AI Customer ServiceThere cannot be a magnetic field outside the capacitor and nothing inside. However, applying this law to surface S2, which is bounded by exactly the same curve ∂ S, but lies between the plates, provides: B = . Any surface that intersects the wire has current I passing through it so Ampère's law gives the correct magnetic field.
It is worth recalling that a charge that is at rest with respect to a static magnetic field incurs no force from that field. From that it follows that the steady-state capacitance should be identical to that of the same capacitor outside the field. Or at least it would follow for a capacitor with vacuum between the plates.
Furthermore, different magnetic loads may require different amounts of capacitors to be used, and the system should only use as many capacitors as needed. Power transistors controlled by a micro controller will be used to coordinate the charging and discharging process.
does a magnetic field change the number of electrons, stored on a capacitor. No, because The purpose of a capacitor is not to store electrons but to store energy. A "charged" capacitor contains the same number of electrons as an "uncharged" capacitor. Electrons don't easily disappear or appear, they have to be moved somewhere.
In the past, creating permanent magnets in labs involved unsafe high energy sources, such as arrays of lead-acid batteries. The goal of this project is to develop a capacitor-based system capable of creating magnets using much lower levels of stored energy, resulting in a safer in-house production process.
From that it follows that the steady-state capacitance should be identical to that of the same capacitor outside the field. Or at least it would follow for a capacitor with vacuum between the plates. If there is a dielectric involved it we could at ask if the presence of the magnetic field has any effect on the dielectric constant of that material.
