I gave you the entire statement.
And you are right, as I wrote there are no magnetic flux because there is no area.
I meant that I've found that we can take an imaginary area and it will give us the same solution. ( See picture -0.016 V)
My questions are why is it true and how can it be explained?
Homework Statement
B = 0.02T
L = 40 cm
w = 10 rad/s
a: Electromotive force between O and C = ?
b: If electromotive force is the same - so what is the velocity?
I found 2 ways of solution. See "3. The Attempt at a Solution "Homework Equations
φ = BA
ε = -dφ(t)/dt
