Question

In a physics laboratory experiment, a coil with 200 turns enclosing an area of 12 $\mathrm{cm}^{2}$ is rotated from a position where its plane is perpendicular to the earth's magnetic field to one where its plane is parallel to the field. The rotation takes 0.040 s. The earth's magnetic field at the location of the laboratory is $6.0 \times 10^{-5} \mathrm{T.}$ (a) What is the total magnetic flux through the coil before it is rotated? After it is rotated? (b) What is the average emf induced in the coil?

Step 1

Given: Number of turns, N = 200 Earth's magnetic field, B = $6.0 \times 10^{-5} \, T$ Area of the coil, A = $12 \, cm^{2} = 12 \times 10^{-4} \, m^{2}$ Initial flux, $\phi_{i} = N \cdot B \cdot A$ $\phi_{i} = 200 \times 6.0 \times 10^{-5} \times 12 \times Show more…
