Magnet Myths and Misconceptions

[picowatt]

Synchro1:

MarkE, Verpies, and myself are correct and you are wrong.  I am sure that Picowatt would join our club also.  What I suggest you do is look over what has been stated and do some searching on those terms and find the information and learn it.  If there are people that are interested in magnetism and the terms "magnetic flux," "magnetic flux density," and especially the term "magnetic field gradient" make you just "zone out" and just skip it, you can't.  Just do the work and hopefully come back better informed.

Agreed,

I particularly liked Verpies' recent posts.  Accurate, succinct, and to the point.

One gauss is also equal to 10−4 kg C−1 s−1. Notice the Kg value in the gauss equation. This represents "Kilograms of pull force".
This value alone is the sole value of magnetic field strength.

No, kilogram is not a unit of force.  Anyway in that formula you have kilograms per second, which is mass change. 
Xavier Borg has even different units for flux density if that amuses you.

Hall effect sensor voltage is directly proportional to the "pull force" of the applied magnetic field.

No, Hall effect sensors can give a high indication even when a piece of iron placed in the same location experiences no linear force.
Ergo, they don't measure the same thing.

Synchro1,

Consider why there is a capital "C" in the cited formula...

Damn I just lost a posting.  I don't know why but it's agony to recompose a posting that you just lost.  In a nutshell I was apologizing because I know that sometimes I flub my units, like "magnetic flux gradient" vs. "magnetic field gradient."  I may sometimes say "magnetic flux" when I really should be saying "magnetic flux density," etc.  I only did this stuff in school, including the bench work.  It was a long time ago.  I don't think and breathe this stuff at all.  As a result my technical vocabulary and the use of the proper technical terms and concepts can be less than stellar at times.  I know the terms and pretty much understand them, but the proper technical prose to describe something does not flow like it does from some of you guys.  Sometimes I will go back to the Hyperphysics web site to brush up but I don't really go that deep.  So I have my own "zone out" threshold.  So I apologize again and please feel free to correct me if I make a mistake.  When in doubt, defer to the really big guns around here.

MH,

Yes, the connection error thing is quite annoying.  Seems to be getting worse.

As for the rest of your post, none of us are infallible.  It is often easy to "misspeak" and worse yet, at my age, I am a bit of a rusty nail when it comes to topics I have not dealt with to any great degree for many years. 

However, the formula Synchro1 posted "One gauss is also equal to 10−4 kg C−1 s−1" to me reads as "One gauss equals 10-4kg per Coulomb per second".  Hopefully someone will correct me if I am wrong, but I believe that is the acceleration a conductor will experience while passing 1 Coulomb at a right angle to a flux of 1 gauss. 

As I said, I could be wrong, so hopefully someone will comment a bit further and better than I...

MarkE?  Verpies?
