| | Well, you're thinking about it wrong. It would be possible to
| |
| |
| |
| |
| | choose
| |
| |
| |
| |
| | units of mass such that the gravitational constant G was
| equal to
| |
| |
| |
| |
| | 1,
| |
| |
| |
| |
| | but that wouldn't make it any less real as a physical
| | constant--similarly, in cgs units, the basic units of charge
| |
| |
| | (emu)
| |
| |
| |
| |
| | Sorry, that should be esu...emu is the unit of magnetic charge
| in
| |
| |
| |
| |
| | cgs units.

| | You might know what you were trying to say both in the original
| | statement and the correction.
| | I doubt if anybody else would.
| | Comment on this garbage, for instance
| | "emu is the unit of magnetic charge in cgs units"
| |

| |
| | OK, magnetic moment, I confused my terms, Jeez. I think you know
| |
| |
| | what I
| |
| |
| | meant.
| |
| |
| |
| | No. I had not the foggiest notion. I still do not know what you
| are
| | trying to say.
| | How about being effective by giving a complete sentence with the
| | phrase "magnetic moment" in its apropriate place.
| | If I were to just replace "magnetic charge" by "magnetic moment",
| the
| | sentence would still be garbage, so I feel sure you must be
| meaning
| | something else.

| | You think the sentence "emu is the unit of magnetic moment in cgs
| units"
| | is garbage? Have a look at this page:
| |
| |
http://www.unc.edu/~rowlett/units/cgsmks.html
| |
| | It says that emu is the unit of the magnetic dipole moment in CGS
| units,
| | and that the conversion from CGS to SI is 1 emu = 0.001
| Ampere*meter^2.
|
| It is wrong. An emu is a unit of current. It is equal to 10 ampere
| SI.
|
| Balls. The emu is a complete system of electrical a=nd magnetic units.
| The emu of current is sometimes called the Abamp. (An abbreviation
| for "absolute Ampere")
| 1 Abamp = 10 Amperes
Ok, sounds good to me. I am sure you have had more experience with it
than me. It just that the writer of the following web pages used e.m.u.
in a context that sounded like an emu was also used as the name for the
emu unit of current.
"...1 e.m.u. of current experiences a force of two dynes..."
