Homework Equations
[itex]l = 0.02 m[/itex]
[itex]r = 0.3 m[/itex]
[itex]E = \frac{d\phi}{dt}[/itex]
[itex]\phi = BA[/itex]
The Attempt at a Solution
[itex]A = \pi 0.32^2  \pi 0.3^2 = 0.0124\pi [/itex] .....Area "cut" by conductor
[itex]\phi = 1.5a_r0.0124\pi = 0.0186\pi a_r [/itex] ....change in flux in one revolution
[itex]1600 rev/min = 1600 rev/ 60 seconds = 1 rev / \frac{60}{1600} seconds[/itex]
[itex] E = \frac{0.0186\pi a_r}{\frac{60}{1600}}[/itex]
[itex] E = 0.496\pi a_r V[/itex]
I'd just like someone to verify this please, and also I'm not sure about which end would be the anode. I think it'd be the end closest the origin, since the magnetic field is in the outward radial direction, [itex]a_r[/itex], the emf induced is in the [itex]a_r[/itex] direction, and thus current would be flowing towards the origin, but I'm not sure if I went about handling the direction vectors the right way.
