Here I explain by 3d animation the most simple case of electromagnetic waves. the uniform plane waves. I explained the maxwell's equations, the concept of uniform plane electric and magnetic fields and their interactions that builds the uniform plane waves

"Engineers do like negative feedback" Excellent.

[@maxwang2537]

It’s a shame this is not watched by far more. Great visualisation. Thank you very much!❤

[@omarmohamed3473]

Best KZbin channel for electrical engineering concepts. Thank you so much for creating these amazing videos! They are so helpful for me!

[@muhammadsohaib6282]

As an avid admirer of TheSiGuy channel, its content never fails to excite and captivate me. Keep up the fantastic work!.❤❤❤

[@yusufcelik1494]

You instantly became one of my favorite KZbin channels. Thank you for this fascinating video

[@ParniaSh]

This video helped me understand plane wave propagation. Thank you so much! Could you please make a video about wave polarization (elliptical, circular etc.)?

[@MohamedEmad-fc7zy]

Thank you for this great effort at simulation and explanation, but there is a small error in the ninth minute 9:11. The direction of the magnetic field inside the magnet must be from south to north(LEFT to RIGHT in the video) and opposite its direction outside the magnet, from north to south. This satisfies Gauss's law, Thus, If we draw a circle at N or S, there must be arrows coming out of the circle. At the same time, Arrows enter the circle

Really usefull to study Antennas and Radiopropagation!!! Thank you

[@ihmejakki2731]

Beautiful animations!:)

[@crossbow170]

Would you consider sharing some of your Manim code? Really love the work and I would love to reproduce some similar animations for my presentations as an electrical engineering student. Love your work! Really good video!

[@user-iz4wt4qb3u]

wow! fantastic!!😮

[@maxwang2537]

15:29 I have a question. Since the rate of change of a sinusoidal function is zero when it’s at it peak and the maximum when it reaches zero, and that the amplitude of the induced field is proportional to the time rate of change of the inducing field, why are the two fields not 90 degrees out of phase but rather always in phase?

[@mrshodz]

can you do an animation of michelson interferometer measure wavelength. how do the wavelengths interact to make rings to measure the wavelength please.

[@mrshodz]

Thanks. The visualisations helps so much. Can you do electromagnetic waves for radio antennas please. Visualized in 3d where your watching from a distance, slicing the EM waves and travelling through the EM waves. Sound waves would be good as well.

[@TheSiGuyEN]

Absolutely appreciate your feedback! Creating 3D visualizations for electromagnetic waves around radio antennas is a fantastic idea. I'll certainly incorporate that into an upcoming video.

[@soundofstreetrecords7843]

Really interesting video! I'm looking to some manim scientific-tutorial in order to make some animation like that, it will be grate if u share some of your knowledge.

[@aarongrossman7109]

PLEASE COME BACK

[@HumbertLaxness]

Finally an explanation that is heavy on visualization.

[@dabdoube92]

Where have you been man ?

[@muhammadsohaib6282]

[@freakmusicaddict]

is the discord server members only now or what happened to it, would be interested to join if it is still active

[@maxwang2537]

Another question. From the style of the animation, looks like it’s made with the Manim tool of 3brown1blue? Thanks.

[@maxwang2537]

I got the answer from the description of the vid. Which is yes.

[@arijitsingh1096]

did you consider plane polarised light ? because if you did not then electric field and magnetic field can oscillate in a any random direction(considering E,B,K) are perpendicular at all instants

[@TheSiGuyEN]

I didn't take polarization into account. I will cover it in another tutorial :)

[@muhammadusman5521]

Are these made with manim?

Yes
