The tesla (symbol T) is a unit of measurement of the strength of a magnetic field.

From here: https://en.wikipedia.org/wiki/Tesla_(unit)

The henry (symbol H) is the SI derived unit of electrical inductance.

From here: https://en.wikipedia.org/wiki/Henry_(unit)

They are clearly NOT the same thing.

@Tinselkoala,

Admitting you don't know something, like the definition of "Negative Micro-Henry" and saking for an explanation is different from stating something that's dead wrong. Look Henry up at the Wikipedia site, and be man enough for once to admit you're wrong.

Here's what you said:

"The Henry and the Tesla have different units".

Lidmotor was right; You just don't understand inductance. You persistently cover your ignorance with chronic abuse. You should be ashamed of yourself.

A Henery equals a Tesla times Meters squared divded by Amperes.

You are the abusive one, synchro, as many many of your own insulting posts demonstrate. And here you are again demonstrating your misrepresentation, strawman arguments, ignorance, and moving goalposts. And it is you that is dead wrong. Again.

Let me remind you what you actually said:

A negative Henry is the equivalent of one Tesla of magnetic strength. Both have positive values.

Now continue to twist and turn, weaseling and trying to deny what YOU YOURSELF SAID. You are worse than Donald Trump !! The Henry and the Tesla have DIFFERENT UNITS, as you have now found out. Your statement is equivalent to saying something like the "kilometer" and the "cubic mile per second per century" are "equivalent". Of course they are not.

And your spelling is atrocious.

(And I doubt very seriously that Lidmotor... who has built some of my circuits and some of whose circuits I have built... ever actually said that to you about me, since I know how you have misrepresented and misquoted and taken things out of context many times before. My understanding of inductance is far superior to YOURS, that is certain, as you continue to prove here yourself with almost every post you make.)

(sic)

And just how does that make the negative of one "equivalent" to the other? I'm almost out of ROFLs but you can have one anyway:

Nor are they even remotely "equivalent", nor is the negative of one "equivalent" to the other.

Except in the deluded mind of someone who thinks he is proving some kind of point.

@Tinselkoala,

So you're quoting Citfa for authority now?

"A flux density of one Wb/m2 (one weber per square metre) is one tesla".

"Henry (H). Henry is the unit of inductance. 1H = 1Wb / 1A ... One ampere-hour is equal to 3600 coulombs".

Here's a question for you: How much magnetic strength will one ampere-hour of current generate in an inductor of one Henry of inductance?

And flux density has nothing to do with henries.  Blah, blah blah.

Give it up Allen.  Every time you post something you show more and more how little you actually know about electricity and electronics.

@Citfa,

Quote from Citfa:

Answer the question I asked in my last comment.

Here's a hint:

A Tesla is a negative Henry with one ampere-hour of current.

Allen,

I really don't understand what your problem is.  If I used your kind of logic I could say a pound is equal to a gallon.  Or an ohm is equal to a watt.  How about a banana is equal to a monkey?  Is that ok with your kind of logic?  You comparisons just don't make sense.  And beside that they have nothing to do with this thread.

I see you just posted another ridiculous comparison after I have already proven to you from the same source you quoted that a tesla and henry are not the same.

You are getting boring.

@Citfa,

You are very, very confused. I wish you would take time to study Inductance and Alternating Current because you're hurting people who are here to learn something about electronics and magnetism more than you can ever know.

Start by returning to comment #708 above and try and work the equation.

Allen I earned a very good living working on industrial level machines for over 30 years.  I have a very good understanding about electronics as I have proven time and time again by showing you where you are wrong.  The only one adding confusion is you with all you comparisons of things that aren't the same.  And when you lose on one you come up with another silly question or comparison.  As I said you are so predictable you are getting very boring.

@Citfa

How do we know you're telling the truth? Anyone can say anything, like I was a Naval aviator who kidded about leading the "Blue Angels". I think you're a liar. You can't understand basic laws of electronics and magnetism. Knock it off. The ruse is up. Everyone can see how little you really know. I'll tell you what's boring is trying to teach you simple basics you perpetually deny.

1.- Negative current is positive current flowing backwards. Basic law of A.C. current that reads negative on the amp meter.

2.- One Tesla of magnetic strength in an inductor of one Henry of Inductance with one ampere-hour of current flowing through it reads as one negative Henry on the inductance meter. The minus sign indicates the level of magnetic strength. The inductance meter in the negative value acts as a gauss meter.

@Citfa and Tinselkola,

Here's what you quoted me as saying:

"Negative current moving backwards is positive current. A negative Henry is the equivalent of one Tesla of magnetic strength".

Just what is it you two fail to understand about that statement of mine at this point?

Teslas are to Henries as Voltage is to Capacitance: T/H: V/C.

Quote from Tinselkoala:

"Now continue to twist and turn, weaseling and trying to deny what YOU YOURSELF SAID. You are worse than Donald Trump !! The Henry and the Tesla have DIFFERENT UNITS, as you have now found out. Your statement is equivalent to saying something like the "kilometer" and the "cubic mile per second per century" are "equivalent". Of course they are not"

If someone said Henries of Capacitance, or Farads of Inductance, they would be guilty of the mistake TK falsely accused me of above.

More insulting and obnoxious abuse from a complete ignoramus named TK:

"Nor are they even remotely "equivalent", nor is the negative of one "equivalent" to the other. Except in the deluded mind of someone who thinks he is proving some kind of point".

Does this rigmarole have a familiar ring to it?

"And here you are again demonstrating your misrepresentation, strawman arguments, ignorance, and moving goalposts".

Another classic from Citfa:

"If I used your kind of logic I could say a pound is equal to a gallon".

The question is; Why don't the moderators scold these chronically abusive insulters and delete their vitriolic rubbish?

You posted a graphic and said that it's the magnetic field for a pancake coil but it's not, it's the magnetic field for a ring-shaped magnet.

I said the magnetic field of a pancake coil,would be the same as that of a ring magnet-and it would be.

@Tinselkoala,

Now you're trying to weasel out of it! Everyone can see you now for what you are.

"Henry (H). Henry is the unit of inductance. 1H = 1Wb / 1A ... One ampere-hour is equal to 3600 coulombs".

That was MHs quote-not TKs.
