Physics, Astronomy & Cosmology / Is there a magnetic "dead zone" somewhere between the two poles of a coil?
« on: 07/06/2008 18:22:53 »
Principle: When using a coil for induction of a longitudinal magnetic field, the appropriate field strength selection is based upon the following formula:
I - Amperes required
KD K - 45,000 amperes turns
I = ---- L - Length of specimen
NL D - Diameter of Specimen (if solid)
N - Number of turns/wraps in coil
Effective area: 18 inches, 9 in. from center of coil/wrap both directions.
Given results: Polarization of aligned electrons in specimen, N at one end, S at the opposite end.
Verified by: Flux field leakage, demonstrated by lines of force at each end of specimen.
Inquiry: Due to the lack of uniformity in most specimens' perimeter profile, Isn't there an existence of a neutrality point (maybe very narrow - almost indiscernible) in the center of the coil between the poles? Since a measurable reduction of applied field strength exists there? And shouldn't there be an established theoretical or industrial standard of identifying the neutral point, as a "Dead Zone"? Or for validity, at the least establish the practice of repositioning specimens?
