Astronauts on a space station decide to use Earth's magnetic field to generate electric current. Earth's B field in this region has the magnitude of 3.0 x 10-7 T. They have a coil that rotates 90° in 1.2 s. The area inside the coil measures 5000 m². Estimate the number of loops needed in the coil so that during that 90° turn it produces an average induced emf of about 120 V. Express your answer in turns.
