## Homework Equations

I used this equation: U = dBS/dt

and then - > (B*r^2*pi*I)/e_0

## The Attempt at a Solution

Resoult should be 7.4 microV

I use the equation that i wrote. The resoult is realy irelevant cus it must be wrong but here it is.So what do you get and how do you get it?

B= 0.65 r = 0.75 * 10^-6 and I = 23 so -> (0.65 * (0.75*10^-6)^2 * pi * 23) / (1.6 * 10^-19) = 1.65 * 10^8 is what i get
