4. Can a conductor manifest Biot-Savart forces upon itself? If so why
does
lightning hit the ground?

If with Q#4, you are asking why doesn't lightning produce a counter-emf,
choking flow to the ground, I would 'guess' that the linear configuration of
a strike, (versus a coiled conductor and therefore its position relative to
its own magnetic flux), and the fact that lightning is DC versus AC
(exhibiting only one full cycle of expanding/collapsing magnetic flux) would
both be contributing factors to a lack of, or at best, infinitesimally small
counter-force. Even in AC inductive circuits, counter-emf can be
designed/used as a positive attribute, limiting flow but not halting it
completely (e.g., start up current of a motor is much higher (LRA rating)
than the FLA rating, which includes the devices self limiting features.

If you're being honest (and I think you are) and you don't feel confident
in
your electrical knowledge, you should go back to page you copied these
questions from and click on "Introduction"
I don't have a favorite color.

I'm simply Jax's warmup act here. I know absolutely nothing about
electricity but I have six questions for you:

1. Why doesn't lightning travel in a helical path since it does traverse
a
magnetic field?

2. Since lightning is a plasma discharge why is it that
magnetohydrodynamic pinching doesn't occur?

3. Does lightning have a magnetic field even though it doesn't travel in
a
close loop? Why?

4. Can a conductor manifest Biot-Savart forces upon itself? If so why
does
lightning hit the ground?

5. What condition must exist between the E and H fields of charge in
ball
lightning or electron clusters to maintain the high charge density?
Remember, like charges repel.

6. What is your favorite colour?

Phil,
Why do you make so many assumptions? Do you do this often? It's a
dangerous
habit and will only cause you embarrassment and heartache. Are you
Jaxie
in
drag? Do you agree with a man who says electricity has nothing to do
with
mathematics and in the same post uses math to describe the potential
of
lightning?
You claim that "they're all fools here" - it seems to me that every
post
has
pointed out the futility in such systems. Did I miss the post you
refer
to?
The fact is that the science teacher claims no 'hidden' knowledge of
electricity, and said only that it follows strict rules of behavior.
Would
you care to argue that point?
The science teacher never claimed to buy into lightning protection on
a

boat, and therefore, has no such system, are you assuming otherwise?
Do
you
see any post in which he defends these systems, or are his questions
merely
conversational in nature? Are you afraid of friendly discussion?
I'll discuss poetry OR electricity with you. You can begin, I'll
respond.
Better yet, stick to posting your boring version of the truth in
politics.
At least then you're easier to ignore.

Jax,

They're all fools here. Some want to insulate their boat but the
ionization
potential renders insulation useless, let alone the effects of
induced
currents; they want to inject ions in the vicinity of their boats,
yet
to
create enough potential to neutralize lightning it would, in fact,
generate
enough potential to cause lightning from their own boats; because
they
don't
understand lightning, electricity, or atmospheric electrodynamics,
they
claim that lightning is magic - defies all physical laws; they want
to
ground their boats to make it part of the lightning discharge
circuit -increasing the chances of getting struck!; the science
teacher
claims some special, hidden knowledge of electricity, but yet is not
practiced in the art, he should stick to poetry. Ah yes the fools
suffer,
some even buy wonder products from the black magicians. God bless
Iron
Joe
of the rusty Faraday cage! What doesn't get him in a thunder clap
will
slowly rot out his hulk by electrolysis.

There's a simple method to reduce the chances of being struck by
many
orders
of magnitude by towing a lightning distraction bouy. It's proven
many
times
over.
