That was awesome n cool...🥺🥺
What you read in books and actually see it.
The part where it gets most interesting is when Mr. Professor cuts slots on the metal.
Respected sir, I have some questions, it would be very helpful if you could answer for me,.... 1)Is it possible to produce em waves by oscillating the magnet to certain frequency?....if possible please explain how it's created sir
2)Can we produce em waves by oscillating the vandegraff generator?what's the difference between em wave produced from magnet, vandegraff,and AC current?
3)where does the energy of em wave come from?where the energy of em wave taken away from??
4) how can an object obsorb the em wave...what does black body do when em wave falls on it,does it produce out of phase light wave which destructively interfere on incident wave...how can a em wave be destroyed?
5)can linearly accelerating, circulating, spinning charge produce light? How will that light look like?
6) does all AC circuits produce em waves, will AC circuit glow visibly when its frequency is frequency of visible light....why DC current does not produce em waves.... even though electrons collide with nucleus of the conductor and losses energy and ACCELERATES?
7)Why cannot neutral objects (Eventhough having positive and negative charge) does not produce em waves ...is it possible to produce em waves by shaking or vibrating the neutral object to certain high frequencies....how black bodies produce em waves??
Thank you sir
good stuff.
I guess we never filmed it but I used to let a student it throw it at my face but the eddy currents would save me.
Best physics teacher in world
Worth mentioning the resistive (Bitter) magnet, after Francis Bitter.
