6. [SF6 20.P.030.] A 95 turn square wire coil of area 0.040 m^2 rotates about a vertical axis at 1730 rpm, as indicated in Figure P20.30. The horizontal component of the Earth's magnetic field at the location of the loop is 2.0 10^-5 T. Calculate the maximum emf induced in the coil by the Earth's field.  (answer in V)
