If you are an Indian using the Word 'India' attached to something that is watched globally, be careful and fully aware of it's Use. Do NOT use that Word casually to generate a Forced Joke.Whatever we speak stays permanently on the Social Media. So use Words carefully. I am an Indian, having already completed my Masters in Computer Science. Now I am chasing Masters in Physics and nowhere had I an Experience where the Teachers were over-Cautious and hyper-panicked. Speak for yourselves and stick to your own personal Experience. Do not generalize it to a complete Nation.

The BD 10 wand that he claims to be a tesla coil is actually a device based on an oudin coil and does not have spinning magnets inside of it. Had it been a tesla coil it still would not have had any moving parts inside.
@lancemgy4 жыл бұрын
Exactly. The buzzing sound is the mechanical interrupter that pulses the current to a little Tesla (Oudin) coil and out comes high frequency high voltage. Otherwise, great presentation!
@uploadJ2 жыл бұрын
re: "and does not have spinning magnets inside of it." Do you know what a motor is, how it operates? A motor is used inside the 'wand' to drive the mechanical interrupter at a very high rate ...
@chrisstrait99442 жыл бұрын
@@uploadJ Yes I am very aware of what a motor is. That is irrelevant because this device does not contain one. I personally own and have worked on multiple of these. There are zero moving parts, the sound it makes is when the electricity arcs across the spark gap preventing the user from making direct contact with the AC source it is plugged into.

@srsa24364 жыл бұрын
eleggance The Tesla coil generates a high potential . The electrode near the coil has a high potential and the one far is at approx 0 potential . So the electrons flow .
@KK-pq6lu2 жыл бұрын
The other end of the Crookes should have been grounded for best effect. He is relying on the leakage of the current through the wood stand and into the air. That is why the green beam is not that sharp and also has a vertical line where the glass standoff is in the middle - the electrons are leaking down the glass standoff and into wood stand. BTW - safety tip, keep that Tesla coil away from those gas jets.
