## Homework Statement

I can't figure out why the unit of Reluctance is At/Wb and not (At/Wb)m

^{2}

This is what I have from my text book, with the red oval area being the part that I'm totally confused about

## Homework Equations

## The Attempt at a Solution

So the m/m cancels out to 1 making it

R=1/(Wb/At·m

^{2})

which is = (At·m

^{2})/Wb

then I have no idea what happened so that m

^{2}vanished and R became At/Wb

Please help me clear up my confusion

I can't sleep scratching my head T_T

Thanks a bunch!
