Lenz's Law states that the direction of induced emf is such that it oppses the vary cause which produces, What is meant by " VARY CAUSE WHICH OPPOSES IT ".
L*(di/dt) + R*i = V*h(t)
subject to i(0) = 0
where L is the inductance and R is the winding resistance, and
i(t) is the instantaneous current.
V is the magnitude of the power source, and
h(t) is the unit step function
A better expression of Lenz's Law is:Lenz's Law states that the direction of induced emf is such that it oppses the vary cause which produces, What is meant by " VARY CAUSE WHICH OPPOSES IT ".
"Some d00d?!?!!"Some d00d discovered that when a conductor moves in a magnetic field, a current is induced in that conductor.
Sometimes these abbreviations lead to a misunderstanding, I am only assuming d00d = dude.Possibly. I just spent some time Googling "d00d" and "some d00d" and my head hurts now.
If Blue Turnip's intent was "K3w1 d00d" then I'll need to draft a retraction. My interpretation of "some d00d" held (and still holds, based on what I dregded up from Google) the connotation of annonymity. I assumed (perhaps unjustly) our Cerulean Crucifer simply didn't care who made the discovery. If my assumption is false, then I offer apology.
