Electrostatic field
Hi,
As you know there is an electrical field around each electrostatic charge. I know how to create an electrostatic field. But I have problem by creating a "variable electrostatic field". Can you give me a guide? Thanks in Advance |

Electrostatic field
Thanks for your answer. But as you know, for example,in a capacitor the electric field exist between the electrodes(blades), or we can say it is ristricted there. what I need is an variable electric field like what we see in a "Van de graaff" (that is limited just from one side). In the other word, I want to have an electric field with this specification that I could change its intensity (variable electrostatic field). for example in the electromagnetic fields, you can change the field's intensity by changing the current of the coil. So do you have any idea for the electrostatic fields?

Saying "static" implies something about charge motion. Common usage for "static charge" simply means that the charge stays after you quit moving around, but it really confuses things later on. I know how to create anelectrostaticfield. But I have problem by creating a "variableelectrostaticfield". Can you give me a guide?If you apply an AC potential to a capacitor, the electricfieldbetween the plates is variable. If you take a charged Leyden jar, and move a magnet rapidly towards and away from the "charging post", the leaves can be made to fluctuate... due to a varying charge on the "leaves". It would be better to leave the word fragment "static" out of "variable electro(static)field", since charge motion is required to achieve this. Even if the motion is very slight. David A. Smith |

Have one, then, if that's what you really want. http://tinyurl.com/y2szhz Find a couple of old TV sets on the scrap heap, take out the LOPTs and Voltage triplers, build a bistable to reverse the field at whatever frequency you like. If you want me to build it for you it will cost you, I'm not cheap. shrug I'll do it with all new components for £10,000. Terms and conditions: Deposit £5000, another £5000 on delivery, price subject to your specification. Is 50,000 V acceptable? |
