For 10 points\--name this process in which a magnetic field can establish an electric current and vice versa.
In 1986 the space shuttle Columbia attempted to study this phenomenon by dragging a 21-kilometer-long conducting tether through the Earth's magnetic field. Since Faraday's law states that it is proportional to the cosine of the angle between a circuit and the magnetic field, it will not occur if the circuit is parallel to a magnetic field.
