@nelsonrochaa,

Thanks for the clarification. Consider this:


"Ørsted discovered the connection between magnetism and electric current when a magnetic field produced by a current-carrying copper bar deflected a magnetised needle during a lecture demonstration".


"In the CGS system, the unit of the H-field is the oersted and the unit of the B‑field is the gauss. In the SI system, the unit ampere per meter (A/m), which is equivalent to newton/weber, is used for the H‑field and the unit of tesla is used for the B‑field".

"H is measured in units of amperes per meter (symbol: A⋅m−1 or A/m) in the SI. B is measured in teslas (symbol: T)".


This is what you need to understand: The H field is an electrical equivalent and the B field a magnetic one.

@Tinselkoala,

You see fit to lecture me on the H and B field?

Lenz's Law:

When a magnet approaches a coil, a current runs in one direction and the ammeter registers a plus indicating a positive current. When the magnet's pulled away from the coil, the current runs in the opposite direction and the ammeter registers a negative indicating a reverse or negative current.

Here we see the negative Henry value on the left, in the "Magnetic Reluctance" equation below. This value is the equivalent of Ohms in the resistance formula on the right and is a measure of magnetic field strength. Naturally, everyone knows the field resists change in current through an inductor and therefore behaves like resistance in the other formula.

Quote from Tinselkoala:

"A negative correlation has nothing to do with "negative Henry" nor does it imply that one or the other of the correlated variables is "negative". By posting what you have posted you reveal that you do not understand correlation or inverse relationships".

Tinselkoala can not find a correlation between the "Inverse Henry" term of magnetic reluctance, and the minus sign that appears before the number on the inductance meter when set to read in Henries. He always couples his misstatements with some kind of personal insult. (He's revealing his stupidity again) to help make his malarkey stick.

Im getting tired of threads being trashed to the point of no discussion at all.

Over at OUR they give the ability to have private discussions where only welcome people are invited. It works well with keeping a thread clean. But some say it stifles free speech. 

Well if you owned a corporation and you have weekly business meetings with say 10 top people in the company, you would not allow a group of protesters to come in and run amuck. It would have nothing to do with free speech as everyone has rights and reasons for privacy. And in this case, the business meeting, we are in that same territory. We have better things to do with our time than deal with protestors. If some dont like the private thread ability, too bad, we dont have to tell you anything. The threads can be also read only for others where protestors can have their opposition thread to babble among themselves, and if the private/read only players 'want' and 'need' to go to that alternate thread to have battle, then so beit, I dont care..

I am talking with others about seeing if Stefan can provide the read only and or private threads so that real work is not interrupted, and the protesters can have their venue to say what they want to say without it being disruptive in the 'work' threads. If it is a private thread and something comes of value from it, then all persons involved in that thread should take a vote as to open a new thread that shows the progress, but have it as read only, where yet again, protestors can have their own rebuttal and abuse delivery threads, fine, sure, go ahead.  So just like a family talking privately at home, all the way to a top gov meeting, we are all entitled to privacy at times, and I do not see that to be a problem in having that here if we want.  If some do not like that idea, then they must not like the idea of having PM abilities, of which is private. So what would be the issue in having private threads when really we could have completely private talks just like a thread in pm, but a thread is just better for many reasons.

@Magluvin,

There are people on this web site, yourself included, who don't understand basic formulas and laws, or choose to twist and misstate them. The rest of us can't accept this level of ignorance coupled with 'High Fashion" technical arguments. It's our duty to expose you as frauds.

I approved this post above to reply to it publicly...

First off, it is mostly you who is saying that we dont understand this stuff. I dont see others agreeing with you here, its just you. You are not building anything to show and prove what you know. You just repeat day after day the same thing. What is that? Are you afraid that if you only wrote it once that nobody will see it?  After 50 times, still worried that nobody has noticed you? As for me, I am not sure that all of the laws and ideals are absolutely correct, so I dont hold them all as gold, otherwise it would be just a "move on folks, nothing more to see here' life. If they are, then this site is here just for giggles and wasted time. You are on moderation. And if you keep it up, as I can see every post before approval, I will do all I can to keep you moderated. There really isnt anyone here that I can see in agreement with your daily splatter.

You say there is fraud. You are only posting cut and paste. Woopty doo. Is that all you got? Do you have bench experience of what you declare as truth? If not then you dont have anything but cut and paste then its worth squat. Like reading a book on kung fu then saying you know kung fu. This isnt the matrix.  So you go ahead and keep posting as you wish, nobody is going to see them.

How about having the threads as read only but the OP of the thread can "allow" or "deny" posting on a user or global basis,, this leaving the need for a moderator to remove any unwanted posts.

I think this would keep the intent of an open community in tact and then using PM you can still have the "closed" discussion when needed.

We already have that in moderation mode. Sometimes it is five or more pages a day and if a moderator isnt around, it could take a bit of time to read, think then approve a waiting message.  So for example, you may have posted 2 days ago and are waiting for approval. Well if its approved, it apears right where it was posted, possibly pages back and possibly days later of which the post may not even get read by someone that has already read that section or page and never get noticed.

Like if there is a read only thread with 5 guys, and if you wanted to join, just ask and if your not a bugger you should be able to join. Its not a prissy private club, its just a way to keep important discussion or project threads clean without having to have the 'job' of running the mop every day. Id rather not have that job and the floors wont get dirty if private or read only threads are allowed.

Like I said before, PM is private and nobody can bother you between important private discussions. But you still have a different navigation of pm than you do with threads. And threads can show pics, pm not. Again if pm is allowed, then there should be no argument against a private thread that allows more convenience to the posters. And if a priv thread dies it should be made public

Lets say I start a thread an set it global read write,, then someone starts posting all the usual garbage.

If I could then set that poster to read only for that thread only it would stop any further intrusion by that poster,, let them start there own thread then to have there say,, like what you are talking about and all of the discussion is out and in the public view.

I take my private stuff and keep most of it in email,, a little PM now and then,, but mostly email. 

If *I* could set that condition for the threads *I* start then no moderator is needed until there are posts that need to be removed,, I would also think that when enough threads are read only for a few posters that they would either change there ways or leave.

Just my thoughts on it.

If all thread makers had that ability, there may be some that are tossed because of things that are not legit and all could get messy and not fair at all.

monitoring threads and responding to complaints as a moderator is not a pleasant biz. Having read only threads I believe is best where all can see but cant disrupt and waste time, of which I really value my time.

Yeah we could all just leave and email eachother. But this site is setup for the convenience of not intermixing like having to sort through messages like email or pms if there is a lot of them. At OUR I think that there is a more happy environment in private and read only threads. Im all for happiness. Businesses succeed better with happy workers and so should a smart group of people trying to find OU in a thread where we dont have to have ANY disruptions and the record of the thread is clean and easily read through.

I really like the idea of read only thread for builders and researchers.  I don't think any of us have anything to hide but it would be nice to carry on a discussion with like minded builders and researchers without all the clutter.  I started a thread at EF just for technical discussion because of this very problem.  Some builders did not want their thread cluttered up with discussion so in respect to that I started that thread.  Sometimes it is used and sometimes not but it is there for use by the ones that want it.

There are a couple of threads there now that are considered builders threads only and most of us that still go to that forum just respect that request.  As far as I know it is not actively enforced by the Admin but just voluntarily respected.  From what I have seen here the voluntary part probably won't work.

If Stefan can set up a read only format with only selected members able to post I do believe it would help this forum a lot.

Respectfully,
Carroll
