Homework Statement
What is the average emf created by a 15 turn cable that is .5 meters in diameter, lies flat with the surface of the Earth and is flipped 180 degrees in 2 seconds?
*Assume the Earth produces a magnetic field of .5 micro Tesla.
Homework Equations
e=-n*r^2*delta B/delta T
The Attempt at a Solution
n=15
delta B=.5*10^-6 minus -.5*10^-6 =1*10^-6 Tesla.
Delta T= 2 seconds
r=.25
e=-.468 micro Volts?
