Vacuum Permeability: SI Base Units, Amps-2 Power

AI Thread Summary
The discussion centers on the correct expression of vacuum permeability units in SI base units. Participants question whether the units provided, such as H•m−1 and A2·s4·kg−1·m−3, are accurate and if they should be expressed as (Amps)-2 power for clarity. There is a focus on ensuring that various unit expressions reduce correctly to basic SI units, specifically kg·m·s−2·A−2. The importance of referencing reliable sources, like Wikipedia, for unit verification is emphasized. Overall, the thread seeks to clarify the proper representation of vacuum permeability in scientific terms.

I got the following for the units of Vacuum permeability:

H•m−1 A2•s-2•kg•m T•m•A-1 N•A−2 V•s•A-1•m-1
Wb•A-1•m-1

Does anyone see anything wrong with these units?

Are the SI base units correct?
A2·s4·kg−1·m−3 in SI base units

Should it be (Amps)-2 power?
 
Physics news on Phys.org
It is hard to read those units (HTML removes multiple whitespace unless you use
Code:
 tags or something similar). Anyway, see [url=http://en.wikipedia.org/wiki/Vacuum_permeability]Wikipedia: Vacuum permeability[/url] for some ways to express those units.
 
H•m−1
A2•s-2•kg•m
T•m•A-1
N•A2
V•s•A-1•m-1
Wb•A-1•m-1

I got these from Wiki but want to know if they are correct

In basic SI units it is
kg \ m \ s^{-2} \ A^{-2}

For the rest, you can easily check the units to see if they reduce to the same expression in basic units. But you don't have to. Just try to find the equation that provides the unit.
For example, if you look at the magnetic induction of the current loop and express the permeability as a function of the other quantities, you find T m /A.
 
Thread 'Is there a white hole inside every black hole?'
This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
