A conducting coil of 2100 turns is connected to a galvanometer, and the total resistance of the circuit is 30 2. The area of each turn is 5.25 x 10-4 m2. This coil is moved from a region where the magnetic field is zero into a region where it is nonzero, the normal to the coil being kept parallel to the magnetic field. The amount of charge that is induced to flow around the circuit is measured to be 8.5 × 10´³C. Find the magnitude of the magnetic field. Number i Units

Refer To: Ref 22-2 Which one of the following statements concerning this situation is true? Since the circuit moves with constant speed, the force F does zero work. The induced current flows clockwise around the circuit. As the circuit moves through the field, the field does work to produce the current. If the circuit were replaced with a wooden loop, there would be no induced emf. The temperature of the circuit remains constant.
In one of NASA's space tether experiments, a 20.0 km long conducting wire was deployed as a power source by the space shuttle as it orbited at 7.86 × 10³ m/s around earth and across earth's magnetic field lines. If the component of earth's magnetic field perpendicular to the tether was 1.16 x 10-5 T, determine the maximum possible potential difference between the two ends of the tether.
At a certain place, Earth's magnetic field has magnitude B =0.806 gauss and is inclined downward at an angle of 71.1° to the horizontal. A flat horizontal circular coil of wire with a radius of 13.1 cm has 939 turns and a total resistance of 73.9 Q. It is connected to a meter with 130 Q resistance. The coil is flipped through a half-revolution about a diameter, so that it is again horizontal. How much charge flows in coulombs through the meter during the flip? Number Units

It has been proposed that extending a long conducting wire from a spacecraft (a "tether") could be used for a variety of applications, from navigation to power generation. One of the first such experiments involving this technique was an August 1992 space shuttle flight, but the tether failed and only only 250 m of the conducting wire could be let out. A 40.0 V motional emf was generated in the Earth’s 5.0 × 10-5 T field, while the shuttle and tether were moving at 7.80 × 103 m/s. What was the angle (in degrees) between the shuttle’s velocity and the Earth’s field?
