In 1996, NASA performed an experiment called the Tethered Satellite experiment. In this experiment a 1.97 x 104-m length of wire was let out by the space shuttle Atlantis to generate a motional emf. The shuttle had an orbital speed of 7.06 x 103 m/s, and the magnitude of the earth's magnetic field at the location of the wire was 4.81 x 10-5 T. If the wire had moved perpendicular to the earth's magnetic field, what would have been the motional emf generated between the ends of the wire?

In 1996, NASA performed an experiment called the Tethered Satellite experiment. In this experiment a 1.60 104-m length of wire was let out by the space shuttle Atlantis to generate a motional emf. The shuttle had an orbital speed of 7.60 103 m/s, and the magnitude of the earth's magnetic field at the location of the wire was 5.10 10-5 T. If the wire had moved perpendicular to the earth's magnetic field, what would have been the motional emf generated...

In one of NASA's space tether experiments, a 20.0 km-long conducting wire was deployed by the space shuttle as it orbited at 7.86 x 103 m/s around Earth and across Earth's magnetic field lines. The resulting motional emf was used as a power source. If the component of Earth's magnetic field perpendicular to the tether was 1.65 x 10T, determine the maximum possible potential difference (in V) between the two ends of the tether. HINT

Tethers are long dangling wires that use the velocity of a spacecraft through the Earth's magnetic field to generate electrical power. Alternatively, electrical currents pushed through the tether might be used to change the spacecraft velocity for either propulsion or for braking and reentry. Several 'space tether experiments have been flown to investigate the possible use if Faraday's law for power generation and/or propulsion. Examples are the 1996 joint US/Italy effort to deploy a 20 km tether from one of...

At one instant, the An astronaut is connected to her spacecraft by a 35-m-long tether cord as she and the spacecraft orbit Earth in a circular path at a speed of 6.5 x 103 m/s. voltage measured between the ends of a wire embedded in the cord is measured to be 0.42 V. Assume the long dimension of the cord is perpendicular to the vertical component of Earth's magnetic field at that instant. (a) What is the magnitude of the...
