You want to use a windmill to generate electricity for your home. You decide to use Earths magnetic field which has a horizontal component B=10^-4 T to an induce emf. You design a conduction loop with 200 turns and surface area of 0.1m^2. The rod is 0.5m wide. On the day you you test your windmill the wind speed was measured to be 100km/hr, assume the windmill rotates at this spped. What is the maximum voltage induced by the wind

Answer 1

100 km/hr is not a rotational speed. Where is the rod located? How is the loop oriented with respect to the field?

I don't get the picture here.
