Are you ready to delve into the fascinating world of magnetic fields? Let's solve some exciting problems together!

Finding Total Magnetic Flux:

To find the total magnetic flux through a coil in a uniform and steady magnetic field, we use the formula Φ = N * B * A * cosθ. In this case, with the field perpendicular to the coil, the total magnetic flux is calculated to be 0.065 Tm² (Option D).

Finding Average Induced e:

When the coil is rotated so its plane is parallel to the field in a certain amount of time, we can calculate the average induced EMF using the formula E = (N * B * A) / t. The average induced e in the coil is determined to be 6.5 V (Option B).
