An instrument based on induced emf has been used to measure projectile speeds up to 6 km / s . A small magnet is imbedded in the projectile, as shown in Figure P 31.14 . The projectile passes through two coils separated by a distance d . As the projectile passes through each coil a pulse of emf is induced in the coil. The time interval between pulses can be measured accurately with an oscilloscope, and thus the speed can be determined. (a) Sketch a graph of Δ V versus t for the arrangement shown
