What is the electric field in a parallel plate capacitor?
28 When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $$ {\bf E}=\frac {\sigma} {2\epsilon_0}\hat {n.}$$ The factor …
electrostatics - Why is electric field in an insulator non zero ...
Jun 4, 2020 · So, one important thing- the fact that the electric field inside a conductor is zero is true only for a perfect conductor, i.e., one which is assumed to have an infinite charge to …
Why does electricity flowing through a copper coil generate a …
Can some one please explain to me why electricity flowing though a copper coil generates a magnetic field or where I could possibly find that information? An electric current (a flow of …
What is the difference between the magnetic $H$-field and $B
the H field is important in electrical engineering. For example, if you take a microwave propagation in a cable, or just a plane wave propagating somewhere, the H field is an analog of a current. …
education - What is a field, really? - Physics Stack Exchange
The mathematics (including "A field is a function that returns a value for a point in space") are the interface: they define for you exactly what you can expect from this object. The "what is it, …
What is the difference between electric field and electric field ...
Dec 2, 2018 · High school textbooks tend to introduce lots of terms nobody else uses. There's no point in distinguishing "electric field", "electric field strength", and "electric field intensity". All …
How do moving charges produce magnetic fields?
A charged particle moving without acceleration produces an electric as well as a magnetic field. It produces an electric field because it's a charge particle. But when it is at rest, it doesn't …
Magnetic field of dipole derivation - Physics Stack Exchange
Jun 11, 2022 · What's interesting is that the above is only the classical field, it's missing a Dirac delta distribution. If you were to try and derive it using two charges instead of an ideal …
Direction of electric field and force - Physics Stack Exchange
Jan 24, 2018 · People then invented a direction for the field itself and said that it doesn't matter what we choose, so let's just choose its direction to be equal to the electric force in a positive …
Why is the magnetic field inside a solenoid constant?
Aug 27, 2011 · The field lines inside the solenoid are in the form of straight parallel lines. This indicates that the magnetic field is the same at all points inside the solenoid.
