    A 25-turn circular coil of wire has diameter 1.00 m. It is placed with its axis along the direction of the Earth's magnetic field of 50.0 μT, and then in 0.200 s it is flipped 180°. An average emf of what magnitude is generated in the coil?

    We know that the induced emf e = - df/dt

    f = NAB = 25 * pi*(0.5m)^2*50*10-6 T = 9.82*10^-4 T m2

    Since we flip it through 180 degrees, the ...
