A 460-turns square wire coil rotates about a vertical axis at 2690 rev per min as in FIGURE 5. The side of the square wire is 3.3 m each. The horizontal component of the Earth's magnetic field at the location of the loop is 37 µT. (i) Calculate the maximum emf induced in the coil by the Earth's magnetic field. (ii) Find the time for the coil to make 3 complete rotations.
