Very proud of this test, first time ever I make it work: it shows in a nutshell the wireless transmission of a small power via #Faraday induction effect, from one coil to a secondary coil which is connected to a voltmeter.
Both coils have >1e4 windings.
First, I let the primary coil have an intermittent current, but nothing happens on the secondary. After I insert a ferromagnet instead, the transmitted tension to the secondary goes to a few +-0.1V.

#Electromagnetism experience of the day in the class: magnetic levitation using a B-field opportunely induced by alternating currents.
(from there, I gave the idea of how levitation works for **trains** , as in the #Maglev https://en.wikipedia.org/wiki/Maglev)

Is there anyone here who is interested in #photonics? If everything goes as expected, I will publish soom as open source a 3D #RCWA tool for the electromagnetic simulation of periodic and nonperiodic structures (#gratings, microstructured solar cells, dielectric #waveguides…). It is written in C++ and represents several years of research and effort. #electromagnetism #simulation

A classical #electromagnetism experiment in this time of the year (i.e. towards the end of my EM course): magnetic breaking acting on a falling magnet (home version).
The left magnet just falls in free fall, the right one gets braked by the induced magnetic field within the aluminum cylinder (mad just sticking together three aluminum foil wraps for kitchen use).
Where is the induced magnetic field coming from? From #Faraday's induction law of course!

A groundbreaking new theory may finally crack the code Einstein spent decades searching for—a unified field theory! Scientists have proposed a geometric model linking electromagnetism and Einstein’s dream, potentially reshaping our understanding of the universe. Science continues to push boundaries, fulfilling century-old dreams.
