Generator for space station Astronauts on a space station decide to use Earth’s magnetic field to generate electric current. Earth’s u B field in this region has the magnitude of 3.0 * 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. Indicate any assumptions you made. Is this a feasible way to produce electric energy?
