Yes, they give it (in SI units) as mass*time^-2*current^-1, which

yields what I wrote above (using the derived-SI unit of Coulombs,

rather than the primary unit of Amps.)

I almost always go back to SI units to do a dimensional analysis check

on any expression I see to make sure the units work out. If they

don't, usually it means there is a constant whose units I didn't apply

correctly, I misunderstood the units of the variables involved, or

else there are hidden constants with units the author didn't include

but which points out my own need to go track it down. There is

another possibility, of course, which is that the author didn't know

what they were quoting well. Which means setting that aside and

looking for better advice.

I'm more of a 'counter' type person. I prefer thinking in terms of

objects I can count, like electrons into Coulomb units, than in terms

of combined units like Amps, which SI prefers because of our ability

to measure, right now. And I keep in mind a few things that also make

sense to me from classical mechanics, like angular momementum which is

easily derived as a necessary consequence of assumed Euclidean space

and linear time, so Joule-seconds are meaningful to me for that reason

and for keeping one idea about electron spin in mind.

So Volts become Joules/Coulomb to me, which is easy to understand from

accelerating electons across a pair of charged plates in a vacuum.

Complete sense there. Ohms are in Joule-seconds/Coulomb^2, Farads are

in Coulomb^2/Joule, and Henries are in Joules-second^2/Coulomb^2.

Clearly, then, the multiplication of Henries and Farads yields

seconds^2, which must be square-rooted to get seconds out. Etc.

I am in the process, now, of going back to understanding Maxwell,

conduction current, displacement current and dielectrics, E fields, H

fields, Poynting vectors, which if I'm guessing right moves me towards

a closer understanding of near-field and far-field, as well (out of

phase nearby moving towards in-phase further out.) I need to factor

in ideas on back-to-back electric charge motion in a loop which from a

distance appears to be no motion of charge at all, quantum

fluctuations (1/2*k*T in each of 3 dimensions), etc. I've never taken

it on and I can see I need/want to. I'd like to get to the point

where I can derive mmf=N*I from a more fundamental understanding.
