Howdy, Richard, We have a new magnetic motor under construction with Paul Sprain. The new electromagnet weighs almost fifty pounds. The whole assembly will probably be 1/4 ton when we finish.
Although we have a high magnetic gradient in the spiral, we are finding that our maximum RPM is limited by the inductance of the electromagnet. The same will likely be the case with your experiment.
From Sparber's favorite site:
http://hyperphysics.phy-astr.gsu.edu/hbase/electric/indtra.html the current in the inductor reaches roughly 2/3rds it's maximum value at L/R seconds. The hard part is determining the value of L. This will tell you whether what you want to do is even possible. Terry On 12/17/06, RC Macaulay <[EMAIL PROTECTED]> wrote:
Howdy Vorts, Been in discussion with some making suggestions for our next series of experiments for water vortex studies. One suggestion was to use the discharge of a high voltage Tesla coil and fire that voltage across spiral wound springs ( 1/2" gap), one of iron and one of aluminum ( a sparkplug if you may). The springs would be mounted inside a clear PVC 4" pipe shrouding the water vortex and the spiral springs configured to approach the shape of the water vortex upward flow. The idea would be to increase the frequency of bursts to the resonant frequency of water. If this would be possible it may supplant the need for an ultrasonic horn configuration and transponder. Hmmm.. Electronic wizards??? can an electronic firing circuit be made that is capable of this number of bursts? My ole model A spark coil, condensor and points don't seem vigorous enough. Richard
