Ex Give Up? B = Hint A levitating train is three cars long (190 m) and has a mass of 100 metric tons (1 metric ton = 1000 kg). The current in the superconducting wires is about 600 kA, and even though the traditional design calls for many small coils of wire, assume for this problem that there is a 190-m-long, straight wire carrying the current beneath the train. A perpendicular magnetic field on the track levitates the train. Check Answer T "K Question Source: Freedman College Physics 3e | Publisher: Macmillan
