I'm sure I'm going to kick myself when someone shows me the way, but there's a limit to how long I can stare at this question...
Determine the maximum magnetic flux through an inductor connected to a standard outlet (ΔVrms = 120 V., f = 60 Hz.)
That's all that's given.
I know that ΔVmax = 120*√2 and ω = 2Πf = 120Π and I think the magnetic flux will be at a maximum when the current is at a maximum, and
Imax = (ΔVmax) / (ω L) so
Imax = (120*√2) /(120ΠL)
Also, ΦB = I*L/N so I get
ΦB = (120*√2) /(120Π N)
but I have no idea what the value of N is for the inductor, & I can't see any way to get rid of that N.
(edited to correct 60 x 2 = 120, not 100 )
