Are My Flux Calculations for Toroids and Solenoids Correct?

[QUOTE="radicaled, post: 4016962, member: 429521"] This is more a theoretical question than a practical one. Basically I want to know if the formulas I arrive for the flux of a Toroid and a Solenoid are correct Leaving aside the integration part this is the basic formula for the flux [itex]\phi = BNA[/itex] B = magnetic field N = number of turns of the solenoid/toroid A = Area So for the solenoid I arrive to this: [itex]B = \mu nI[/itex] -> n = N/L [itex]A = 2\pi r(r+l)[/itex] this is the area for a cylinder [itex]\phi = \mu nINA = \frac{\mu IN^{2}}{L}2\pi r(r+L)[/itex] For the toroid I arrive to this: [itex]B = \frac{\mu NI}{2\pi r}[/itex] [itex]\phi = \int BNdr = \frac{\mu IN^{2}}{2\pi}ln\frac{b}{a} [/itex] [/QUOTE]
