Greetings every one, this will be my first real post I hope you all find it interesting and enlightening, I am a private researcher and currently a college student, I've been replicating Tesla, Bendini, and Stiffler projects for quite a while and I've decided to share some of the knowledge that I've learned, hope it helps.
Firstly in order to understand this concept you kneed to know how a spinning toroid or smoke ring is created. So first of if you have ever smoked and you know how to make smoke rings you would first breath out a cloud so that its traveling at a reasonable velocity, they you would sharply inhale, this causes the cloud to be formed into a spinning ring, that will carry the smoke for quite a distance before it breaks up.
Now to apply this to electronics, suppose we have very large secondary with many turns of fine wire, and a secondary out of 2 or 3 turns of large gauge wire. We start off by tuning the signal in the secondary to 1/4 wave length. Now as we watch the coil we see a electromagnetic field build up around the coil and then the primary suddenly shuts off but the field on the secondary is still there (this is because the secondary has many more turns and its inductance is much higher therefore the change in the em field will be much slower) as the primary shuts off there is a back emf because there is no longer voltage being applied to the coil, this is the smokers sharp inhale that creates the spinning ring, and likewise a spinning ring of em energy is created that can travel a great distance without being broken up(this works best when the primary is driven at 1/4 wave length of the secondary). If this em ring strikes a mass the energy will be released in the substance it strikes, if it is conducting a large current will occur.
Now the shape of your coil is very important for creating the spinning ring. For a coil wound on a pipe where the sides a perpendicular the spinning ring is created on the normal of the coil sides, basically the spinning ring only increases in diameter and does not travel in the upward or down ward directions. However suppose we had a coil that wound on a cone with the edges 45 degrees apart the ring will travel upwards with increasing diameter at the same rate. now suppose that we had a pancake coil wound on a flat surface, this would create a ring that travels upward at a very high velocity without increasing in diameter, this wave will be able to travel very far before its energy is released to the surroundings, its the basis for Tesla's Death ray and wireless transmission of energy.
Any way I hope this helped some of you, I would have posted pictures of these devices in action but at the moment I don't have a camera please comment I would like to know what you think
