I have a capacitor with stacked dielectrics where $d_1 =10^{-3} \ m$ , $\varepsilon_{1} = 7$ and $d_2 =0.5 \cdot 10^{-3} \ m$ , $\varepsilon_{2} = 2$ and $V = 500V$ . How would I go about calculating the electric field intensity in each dielectric? I know that I can treat the capacitor as 2 capacitors connected in series. I can get $E = Vd$ and $V = E_1d_1 + E_2d_2$ but I don't know how to get th…

These mini lightning bolts have been known for millennia. Understanding static electricity at the atomic level opens the door for new technologies – as well as ways to cut down on the tiny zaps.

A wireless transmitter uses almost no power and at first glance appears to violate the laws of physics. It’s actually a clever use of physics that could one day transmit data from tiny remote sensors.

If an electron is continuously moving, why doesn’t it continuously emit electromagnetic radiation? If an electron is accelerating in an atom, why doesn’t it radiate energy according to Maxwell’s ...

i know the electron are not the one to transfer energy and that the electric and magnetic field are the ones doing the job but why is the field created in the first place and even the "energy flowing with the fields" is still pretty abstract to me

I created a new simulation project called ' Relation between Maxwell 1st eqn and gauss law ': A short form video on why,how and what we need in both More of my public projects can be found here .

partial^AA' phi_AB =.0. I need some hints on how to find suitable components of phi_AB in terms the components of the electric and magnetic fields. Thanks.

This manuscript develops a mathematically disciplined version of the electromagnetic motherboard hypothesis. It does not assert that all gravitational curvature is electromagnetic in origin. Instead, it advances a focused and testable claim: in a wide class of physically important systems—plasmas, jets, accretion flows, magnetospheres, radiation fields, and atomic structure—electromagnetic fields…

Erik Bard went looking for a rational answer—and found a strange electromagnetic clue.

In classical electromagnetism, the continuous charge distribution is a model that treats electric charge as a quantity that can be determined in a particular region $R$. I think that the electric ...

While a lightning strike occurs between a cloud and an object on or near the ground, it takes the path of least resistance, which means it moves towards the closest object with the highest electric potential
