UNDER COSTRUCTION
THE CASE OF COLLINEAR
CONDUCTORS AT A DISTANCE, NOT OVERLAPING
ASSUME AN ELECTRIC CURRENT I IS GOING
THROUGH SECTION B . THEN THE MAGNETIC LINES OF B ARE
CROSSING C. NOW
ASSUME THAT THE CURRENT THROUGH B IS
ALTERNATING. THEN AN INDUCED POTENTIAL WILL RISE AT THE ENGS
OF B. AS NO MAGNETIC LINES OF B WILL CUT SECTION A, NO
THEORETICAL INDUCED
POTENTIAL WILL RISE AT TH ENDS OF SECTION A, ACCORDING TO THE
FARADAY LAW OF
INDUCTION,
NEVERTHELESS, EXPERIMENT SHOWS
THAT A POTENTIAL IS INDEED INDUCED.
IMPORTANT:
THE POTENTIAL MEASURMENT
IS CURRIED
IN SERIES IN THE MIDDLE OF
CONDUCTOR “A”
“A” conductor
and ac meter
OR
SO THAT, IT DOES NOT FORM A
SUBSTANTIAL LOOP.
SO,
IN THIS CASE, THE FARADAY LAW OF INDUCTION,
Ε=-dΦ/dt, with
Φ=Β.S, internal product,
IS
NOT CORRECT AND APPLICABLE…
FEYNMAN’S
EXPERIMENT FALSIFYING THE FARADAY LAW.
WE READ FROM FEYNMAN, NOBEL LAURETE
:
A counter example to Faraday's Law when
over-broadly
interpreted. A wire (solid red lines) connects to two
touching metal plates
(silver) to form a circuit. The whole system sits in a
uniform magnetic field,
normal to the page. If the word "circuit" is interpreted
as
"primary path of current flow" (marked in red), then the
magnetic
flux through the "circuit" changes dramatically as the
plates are
rotated, yet the EMF is
almost zero, which
contradicts Faraday's Law. After Feynman Lectures on
Physics Vol. II page 17-3
CONTINUOUS… see about AMPERE'S
LAW AND HOW, IT EXPLAINS PERFECTLY THIS CASE,
INSTEAD OF USE OF THE ARBITRARY AND EMPIRICAL FARADAY LAW.
